Abstract
The invention discloses a method for measuring the content of suspension sulfur in a desulphurization solution. The method comprises the steps of putting a medium speed quantitative filter paper for measuring the suspension sulfur in a weighing bottle; opening a bottle cap; putting the weighing bottle in a drying oven; drying the medium speed quantitative filter paper; taking out the weighing bottle; closing the bottle cap; weighing; taking the medium speed quantitative filter paper out from the weighing bottle; pouring 100 mL mixed desulphurization solution on the medium speed quantitative filter paper for filtration; filtering; putting the medium speed quantitative filter paper into the weighing bottle again; opening the bottle cap; putting the weighing bottle in a drying oven for drying; taking out the weighing bottle; cooling the weighing bottle; closing the bottle cap; weighing; and subtracting the former weight by the obtained weight, so that the content of the suspension sulfur in the desulphurization solution can be obtained. The method has the advantages of convenient operation, simple process flow, safe and reliable operation, low manufacturing cost, high accuracy of the measured data, etc. The method can save manpower and material resources.
Description
Technical field
The present invention relates to a kind of method of measuring the suspension sulfur content, particularly a kind of method of measuring suspension sulfur content in the doctor solution.
Background technology
Suspension sulphur is high in the doctor solution in commercial production, affects the desulfurized effect of doctor solution, if measurement result is inaccurate, does not instruct production, so the measurement result of suspension sulphur is very important; The method of measuring suspension sulphur in the doctor solution in the prior art is to measure suspension sulphur with the vacuum pump suction filtration, but draft is excessive, just easily the middling speed quantitative filter paper is taken out leakage, be difficult to guarantee the accuracy of data, and in the suction filtration process, be with easily liquid, damage vacuum pump, the loss that brings equipment, thereby cause analysis cost higher, so the method for suspension sulfur content or not ideal enough in the existing measurement doctor solution.
Summary of the invention
The objective of the invention is: provide a kind of method of measuring suspension sulfur content in the doctor solution that a kind of easy to operate, technological process data accuracy simple, that measure is high, use manpower and material resources sparingly, reduce cost, to overcome the deficiencies in the prior art.
The present invention is achieved in that a kind of method of measuring suspension sulfur content in the doctor solution of the present invention is, the middling speed quantitative filter paper that at first will be used for measuring suspension sulphur is put into measuring cup, after opening bottle cap measuring cup being put into baking oven oven dry, the taking-up measuring cup is built and is weighed, then take out the middling speed quantitative filter paper, 100 milliliters of doctor solutions that shake up are poured on the middling speed quantitative filter paper filter, after the filtration, the middling speed quantitative filter paper is put into measuring cup, opening bottle cap puts into baking oven with measuring cup and dries, take out after the measuring cup cooling, building bottle cap weighs, alleged weight once before the weight of gained of weighing this moment deducted can obtain the content of suspension sulphur in the doctor solution.
Be 78 ± 2 ℃ with the Temperature Setting of above-mentioned baking oven, and in the time will opening measuring cup bottle cap and that the middling speed quantitative filter paper is housed and put into baking oven and dry, its drying time it is 25～35 minutes.
Owing to adopted technique scheme, the present invention at first will take out for the middling speed quantitative filter paper that filters and put into measuring cup, open bottle cap, put in the baking oven 30 minutes, the temperature of baking oven is transferred to 78 ± 2 ℃, then take out, the measuring cup bottle cap is built, claimed its weight; Get 100 milliliters of the doctor solutions that shake up this moment, directly filter by the middling speed quantitative filter paper, by the time after having filtered, take gently the middling speed quantitative filter paper in the measuring cup, the weighing bottle cap opened in being put into baking oven dry, the temperature of baking oven is transferred to 78 ± 2 ℃, takes out after 30 minutes, the weighing bottle cap is covered in the cool drying weighing, until constant weight gets final product result of calculation.The present invention compared with prior art, that the present invention not only has is easy to operate, technological process is simple, safe and reliable to operation, advantage that cost of manufacture is low, the data accuracy of measurement is high, the advantage such as use manpower and material resources sparingly but also have.
Embodiment
The present invention is described in further detail below in conjunction with embodiment, but not as limitation of the present invention.
Embodiments of the invention: when implementing a kind of method of measuring suspension sulfur content in the doctor solution of the present invention, after at first opening bottle cap measuring cup being put into baking oven oven dry, the taking-up measuring cup is built and is weighed, then take out the middling speed quantitative filter paper, 100 milliliters of doctor solutions that shake up are poured on the middling speed quantitative filter paper filter, after the filtration, the middling speed quantitative filter paper is put into measuring cup, opening bottle cap puts into baking oven with measuring cup and dries, take out after the measuring cup cooling, building bottle cap weighs, alleged weight once before the weight of gained of weighing this moment deducted, can obtain the content of suspension sulphur in the doctor solution, the temperature of its baking oven preferably is set as 78 ± 2 ℃, and will open bottle cap, and the measuring cup that the middling speed quantitative filter paper is housed is when putting into baking oven and drying, and its drying time preferably is controlled in 25～35 minutes the scope.
Middling speed quantitative filter paper of the present invention, measuring cup and baking oven are existing equipment.
The used middling speed quantitative filter paper of the present invention is mainly used in qualitative chemical analysis and corresponding isolated by filtration and makes the test paper of corresponding purity, as raw material take the senior cotton of high-quality, use the paper making equipment essence of advancing of modern unique paper technology and elder generation to make and form, be that a kind of clarity is high, even tissue and have the textile paper of certain filter velocity and some strength, product is widely used in the departments such as scientific research, industry, agricultural, medical and health and environmental protection and is used as qualitative and quantitative analysis and qualitative, quantitative chromatographic analysis and test; Measuring cup is the vial of the tubular of grinding port plug, is used for the container of minusing weighing sample.
The present invention adopts the middling speed quantitative filter paper directly to filter, after the constant temperature constant weight, not only the accuracy of data is high, and general glass funnel can both satisfy the mensuration requirement, cost is lower, operation steps is simple, and test of many times is measured, and its measurement result is very parallel, through constantly test, tackling key problem, analytical approach of the present invention compares with analytical approach in the past, and the data precision that analytical approach of the present invention draws is high, and can find exactly the practical problems that exists producing, the operative employee is according to determination data, can regulate better the content of suspension sulphur in the doctor solution, not exist and often repair as before pump, buy the situation of pump, saved manpower, material resources.Reduced cost of determination again correct guidance production, the economic benefit of bringing like this is immeasurable.
