Background technology
Add anticaking agent in the multi-hole nitramines and can change granulation mechanism; and can effectively suppress the multi-hole nitramines caking; but the use cost of anticaking agent in order to control the consumption of anticaking agent, detects the content of anticaking agent in the multi-hole nitramines than higher with certain analytical approach in the production practices.Traditional porous ammonium nitrate anticaking agent analytical approach is to adopt the Soxhlet extraction process, and this ratio juris is: make organic solvent with isopropyl alcohol or phenixin, continue heating and the anticaking agent in the multi-hole nitramines was extracted in 6-8 hour under 70 ℃ of-80 ℃ of temperature.Extracting finishes the back and adopts vacuum evaporation 1.5-2 hour that organic solvent evaporation is complete, and last weighing grease is the quality of anticaking agent.This method exposes a lot of shortcomings, and at first the Soxhlet extracting generally needs 6-8 hour, and consuming time long, whole test is finished needs about 10 hours, can not instruct production fast.Whether the technology that adopts vacuum evaporation to remove in addition to desolvate is not really perfect, can not accurately judge organic solvent and remove totally, and it is bigger to take weighing method to calculate anticaking agent content error at last.The anticaking agent consumption of general multi-hole nitramines is at 800-1000ppm, and the error of analytical balance weighing is very big.Therefore the Soxhlet method for extracting exists: one, length consuming time, two, complex operation step, three, defective such as accuracy is low.
Summary of the invention
Purpose of the present invention provides the method for anticaking agent in a kind of quickly analyzing porous ammonium nitrate for defectives such as the length consuming time, inconvenient operation, the accuracy that overcome conventional Soxhlet extraction process and have are low.This method adopts spectrophotometric method can quick and precisely analyze the content of anticaking agent in the multi-hole nitramines, brings very big facility to production.
The present invention realizes in the following manner:.
A kind of method of quickly analyzing porous ammonium nitrate anticaking agent, mainly carry out according to following steps:
(1) testing sample preparation: accurately take by weighing 50g and contain the multi-hole nitramines sample dissolution of unknown quantity anticaking agent in 50ml isopropyl alcohol organic solvent;
(2) sample dissolution and filtration: the multi-hole nitramines sample after will dissolving is cooled to room temperature after placing 50 ℃ of constant temperature water baths to be incubated half an hour, then with sample filtering;
(3) anticaking agent standard solution preparation: accurately take by weighing the 0.025g anticaking agent, dissolve and be diluted to 250ml with a small amount of isopropyl alcohol, it is 0.01mg/ml that this standard solution contains anticaking agent;
(4) typical curve is drawn: measure 0.0,1.0,2.0,4.0,6.0,8.0ml anticaking agent standard solution places 100ml volumetric flask and constant volume respectively, preparation massfraction 0.00,100ppm, 200ppm, 400ppm, 600ppm, the series standard solution of 800ppm is measured the absorbance of each standard solution under the 308nm wavelength, make the typical curve of this anticaking agent, and to try to achieve computing formula be Y=Kx+b; Wherein x is an absorbance, and Y is the anticaking agent amount;
(5) testing sample analysis: the testing sample solution after step (2) filtration is analyzed its absorbance A under the wavelength of 308nm, try to achieve the anticaking agent amount according to the computing formula of step (4).
The method of anticaking agent content is in the quickly analyzing porous ammonium nitrate provided by the invention: comprise The pretreatment and heating for dissolving, measure the absorbance of each standard solution under suitable wavelength, make the typical curve of this anticaking agent, obtain the computing formula several steps.
The present invention can be used for the analysis of multi-hole nitramines, composite fertilizer or artificial fertilizer anticaking agent.
The present invention compared with prior art, its advantage mainly comprises:
One, shorten analysis time, traditional Soxhlet extracting needs about 10 hours, and the about 1h-1.5h of present analytical approach has shortened analysis time greatly.
Two, operation steps is simple, and traditional method needs a plurality of steps such as Soxhlet extracting, vacuum evaporation, constant weighing, only needs sample preparation and spectrophotometer analysis now, easy operating.
Three, accuracy height, traditional method running time is long, complex steps, source of error is extensive, and present analytical approach adopts spectrophotometric method sensitivity very high, can be used in a small amount of and micro-example analysis.
Embodiment
The invention will be further described below in conjunction with embodiment.
A kind of method of quickly analyzing porous ammonium nitrate anticaking agent, carry out according to following steps:
(1) testing sample preparation: the multi-hole nitramines sample dissolution that contains anticaking agent that takes by weighing article number that 50.012g buys from flower king (Shanghai) trade Co., Ltd and be FA80N is 50g isopropyl alcohol organic solvent;
(2) sample dissolution and filtration: the multi-hole nitramines sample after will dissolving places 50 ℃ of constant temperature water baths to be cooled to room temperature after half an hour, then with sample filtering;
