Description
One. technical field: the utility model relates to a kind of indium and measures utensil, particularly relates to a kind of indium colorimetric testing tube.
Two. background technology: indium is not animals and plants and necessary for human body trace element, it in animal body physiological action it be unclear that.The white mouse test of indium shows, sucks 30mg/d and produces poisoning, and sucking 200mg/d can cause death.The abundance value of indium in the earth's crust is 0.1mg/kg.The content range of indium is 0.7～3mg/kg in world's soil, and median is 1mg/kg.The concentration of indium is about 0.00011mg/L in the seawater.In nonferrous metal mine exploitation and smelting process, often there is a large amount of indiums to be discharged in the water environment, thus the accident of polluting.
Classical indium assay method is the extraction graphite oven atomic absorption, and its operation steps is:
1. water sample is cleared up
(1) accurately pipette an amount of water sample (indium content is less than 0.4 μ g) in beaker, add liquor ferri trichloridi 0.5mL, concentrated hydrochloric acid 5mL, when on electric hot plate, being evaporated to about 5mL, adding (1+1) sulfuric acid 15mL, low-grade fever is dissolved issuable residue.Change in the 50mL color-comparison tube, be cooled to room temperature, add pure water 15mL, potassium bromide solution 2mL placed 5 minutes, added 5mL phosphoric acid, added water and was settled to 50mL.Accurately add methyl isobutyl ketone (MIBK) 5mL, jolting 3 minutes, standing demix.
(2) organic phase is to be measured, replaces water sample with pure water simultaneously, carries out blank test.
2. the drafting of typical curve
(1) in six 50mL beakers, adds 0mL, 0.05mL, 0.10mL, 0.20mL, 0.30mL, 0.40mL indium standard operation solution respectively, add liquor ferri trichloridi 0.5mL and concentrated hydrochloric acid 1mL again, put and steam on the electric hot plate near doing, add (1+1) sulfuric acid 15mL, the low-grade fever dissolving changes in the 50mL color-comparison tube, be cooled to room temperature, add water to about 35mL, add potassium bromide solution 2mL again, shake up.Below operation is cleared up with step 1 water sample.
(2) get organic phase and advance the absorbance that graphite furnace is measured indium, behind blank correction, draw absorbance-concentration curve.
(3) measure simultaneously that water sample is cleared up after the organic phase that extracts.Deduct the absorbance of omnidistance preface blank by the absorbance of sample, find the content of indium the sample, calculate the concentration of indium in the water sample from calibration curve.The problem that the extraction graphite oven atomic absorption exists:
(1) must use indium standard solution, a large amount of sulfuric acid and organic reagent, the people is for causing environmental pollution.
(2) operating process such as drafting of the preparation of sample, typical curve are tediously long, loaded down with trivial details, and labour intensity is big.
(3) must measure absorbance and, operator quality be required height, testing cost costliness by the use large-scale instrument with formula calculating concentration value.
Three. the utility model content:
The utility model purpose:, make a kind of easy to carry, indium colorimetric testing tube of using simple and fast at disadvantages of background technology.
The technical solution of the utility model:
A kind of indium colorimetric testing 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 indium determining liquid is housed in glass tube, measures the height H of liquid in glass tube
