Description
One. technical field: the utility model relates to a kind of beryllium and measures utensil, particularly relates to a kind of beryllium colorimetric testing tube.
Two. background technology: beryllium and toxicity of compound thereof are extremely strong, even also can conjunctiva, cornea are inflamed owing to local excitation injures skin, mucous membrane on a small quantity, cause diseases such as pulmonary emphysema, pneumonia.Because the toxicity of beryllium is extremely strong and continuous action is also very strong, even if suck the trace beryllium people is poisoned, suck more beryllium people's death by poisoning is died.The industrial pollution source of beryllium mainly comes from the factory effluent of industries such as smelting, mining and feature material, radio component parts and instrument part.
The method of traditional test beryllium content is the chrome azurol S photometry, and its operation steps is:
(1) the sample pretreatment water sample that will contain large amount of organic is cleared up with nitric acid-sulfuric acid, has interfering material to exist or the extremely low water sample of beryllium content activated charcoal separation and concentration.
(2) sample determination is got an amount of water sample in color comparison tube, is adjusted to faintly acid, adds Na successively
2-EDTA solution 2mL, 0.1% chrome azurol S 2mL, ammonia buffer 5mL, cetylpyridinium chloride 1mL adds the 150mg activated charcoal behind the mixing, stir evenly the back and placed 10 minutes, with the filtration of bleeding of the speed of 10mL/min, discards filtrate.The 25mL color comparison tube is put into bottle,suction, and the hydrochloric acid 6mL that seethes with excitement with 2mol/L divides dropping detergent active charcoal three times, uses low amounts of water detergent active charcoal again, gives suction filtration after every dropping once.Take out color comparison tube, add 1 of phenolphthalein solution in pipe, be neutralized to the micro-redness of solution with 1: 1 ammoniacal liquor, the HCl residual titration with 2mol/L just disappears to red again.Heating is 5 minutes in 60 ℃ of water-baths, takes out and places 30 minutes.Measure absorbance at the 618nm place with the 20mm cuvette.After the absorbance by the absorbance deduction blank sample of measuring gained, find the content of beryllium, by formula calculate beryllium content in the sample then from typical curve.
(3) a drawing standard curve peek color comparison tube adds the beryllium standard solution respectively, by the above-mentioned steps operation, and draws through the absorbance of the blank correction typical curve to beryllium content.
The problem that the chrome azurol S photometry exists: (1) needs to use the beryllium standard solution, and artificial pollutes, and harmful; (2) in the mensuration process, use varieties of reagent many, palpus separation, enrichment and heat treated, complex operation, complexity; (3) need with the Instrument measuring absorbance and with formula calculating concentration value, high to the operator quality requirement, the testing cost costliness.
