Description
One. technical field: the utility model relates to a kind of copper and measures utensil, particularly relates to a kind of copper colorimetric test tube.
Two. background technology: copper is very big to aquatic organism toxicity, and its toxicity is relevant with its form in water, and the toxicity of free state copper ion is than big many of the toxicity of complex state copper ion.Copper ion is 0.6mg/L to the critical harm concentration of paddy rice in the irrigation water.Because the existence of copper ion causes crop products to be polluted.The main pollution source of copper is in the waste water of dischargings such as industry such as plating, smelting, five metals and petrochemical complex, chemical industry.
At present, traditional copper content test method has atomic absorption spectrophotometry, cupral extraction spectrophotometric method etc.The basic step of cupral extraction spectrophotometric method is:
1. colour developing extraction
Draw an amount of sample in the 125mL separating funnel, add water to 50mL, add the 10mLEDTA-ammonium citrate, 5mL ammonium chloride-Ammonia shakes up.
Add 0.2% cupral solution 5mL, shake up, left standstill 5 minutes.
Add the 10mL phenixin, firmly duration of oscillation is no less than 2 minutes, leaves standstill, and waits for layering.
2. measure
Inhale the moisture content that removes the funnel neck with filter paper, fill in one little absorbent cotton, discard the phenixin phase 1～2mL of initial outflow, then phenixin is put into mutually the cuvette of 20mm drying, as reference, measure absorbance in 440nm wavelength place with phenixin.Replace sample with 50mL water, carry out blank test simultaneously by above-mentioned steps, deduct the absorbance of blank sample with the absorbance of sample after, find the content of copper from typical curve.
3. the drafting of typical curve
In 8 separating funnels, add 0mL, 0.20mL, 0.50mL, 1.00mL, 2.00mL, 3.00mL, 5.00mL respectively, 6.00mL copper standard is used liquid, adds water to 50mL, be made into one group of standard serial solution, developing the color by the aforesaid operations step then extracts and measures.After the absorbance that records made blank correction, again with corresponding copper content drawing standard curve.
The problem that the cupral extraction spectrophotometric method exists:
(1) employed copper standard solution and phenixin etc. can cause secondary pollution.
(2) operating process such as drafting of extraction and typical curve are tediously long, complexity, and labour intensity is big.
(3) need to use the Instrument measuring absorbance also with formula calculating concentration value, high to the operator quality requirement, the testing cost height.
(4) extraction and colorimetric operating process are wanted rapidly, in order to avoid resultant of reaction decomposes under light.
(5) in the test process, disturbing factor is many, deals with improperly and causes test error easily.
Three. the utility model content:
The purpose of this utility model is: at disadvantages of background technology, make a kind of easy to carry, copper colorimetric test tube of using simple and fast.
Technical solutions of the utility model are:
A kind of copper colorimetric test tube is vacuum sealing tube, contains the uniform cross section glass tube of end sealing, and the opening part of glass tube is communicated with transition section with the kapillary of end sealing, and copper determination solution is housed in glass tube, measures the height H of liquid in glass tube
1With the glass tube uniform cross section height H of leaving a blank
2Ratio be H

Described copper colorimetric test tube, the height H of mensuration liquid in glass tube
1With the glass tube uniform cross section height H of leaving a blank
2Ratio be H
1: H
2=1: 5～7.
Positive beneficial effect of the present utility model is:
1. the utility model is with the detection technique commercialization, and commercialization is loaded on the mensuration fluid-tight for preparing in the glass tube with vacuum, can directly use.Only need during operation to fracture in the water sample to be measured capillary tube segment of test tube makes in the water sample automatic ration tail pipe to be measured and measures liquid generation metachromasia, with the contrast of standard color range, just can draw copper content more accurately in 5～10 minutes behind the colour stable.Need not be when each test preparing standard solution, reagent, can simplify the detection step greatly, save minute, reduce workload, reduce labor intensity.
2. it is reasonable that the utility model is measured formula of liquid, advanced technology, and stable performance is used simple.Adopt standard sample liquid to react with it in advance, constant color forms permanent colour code standard, and encapsulation forms the contrast color range, carries out the scene and detects, and need not to prepare other any reagent, and testing result accurately and reliably.The standard colour code can be made by standard color range pipe of the present utility model and form, also can be, or the colored printing cardboard, or the colored plastic rod by the computer color atlas, or other physical medium material such as stained glass goods forms, and uses very convenient.
3. compare with traditional cupral extraction spectrophotometric method, the utility model has reduced measuring process, has accelerated finding speed.
4. to measure the chromogenic reaction of liquid and determinand copper be to carry out automatically under given conditions the glass tube with vacuum to the utility model, can effectively avoid accidental error and personal error, testing result meets the requirement of water analysis error precision accurately and reliably, and detection limit meets national potable water requirement standard.
