Description
One. technical field: the utility model relates to a kind of boron and measures utensil, particularly relates to a kind of boron colorimetric test tube.
Two, background technology: boron is the nutrient of plant growth, and the floristics difference needs the boron amount that very big-difference is arranged.The critical concentration of boron deficiency is 0.50～5.0mg/L concerning general crop, but the irrigation water boron content is harmful to again certain plants when surpassing 2.0mg/L.There is a small amount of or higher boron to exist in bittern and some mineral water.Require boron content to be no more than 1mg/L as potable water, can influence central nervous system because the people takes in a large amount of boron, long-term absorption can cause borism.
The conventional test methodologies of boron is the curcumin photometry, and its operation steps is:
1, sample pretreatment: to boron content is that the water sample of 0.10～1.0mg/L is got 1.00mL, if the water sample boron content is too high, then should dilute earlier.If boron content is low excessively, can draw more water sample, move in the evaporating dish, add a little aqua calcis, after making it to be alkalescence, in water-bath, be evaporated to dried.The 0.1moL/L hydrochloric acid solution that adds proper volume makes dissolving, draws 1.00mL and measures.If the water sample muddiness can be filtered.
2, sample determination
(1) colour developing: draw the 1.00mL water sample in 50mL tygon cup, add 4.0mL curcumin-oxalic acid solution, rotate the tygon cup gently and make it to mix, evaporate in 55 ℃ ± 3 ℃ the water-bath absolutely dry after, continue to keep 15min in water-bath, take out cooling.With solids dissolving in the cup, and clean wall of cup with 95% ethanol, solution moved in the 25mL volumetric flask with sticking plaster, with 95% ethanol dilution to graticule.
(2) measure: use the 10mL cuvette, at 540mm wavelength place, replace water sample with distilled water, carrying out blank test solution with the identical operations step is reference, measures absorbance., to graticule, in 1 hour, measure with ethanol dilution.
3, the drafting of calibration curve: draw quite every milliliter respectively and contain HBO
20.005mg standard solution 0mL, 0.10mL, 0.20mL, 0.30mL, 0.40mL, 0.60mL, 0.80mL, 1.00mL mend and to add water to 1.0mL in 50mL tygon cup, below develop the color and measure by the sample determination step.
4, by formula calculate boron content.
The problem that the curcumin photometry exists: (1) disturbing factor is many, common elements Ca, Mg, NO in the water
3 -Produce interference Deng all, remove trouble; (2) reagent instability, the palpus matching while using, running program is loaded down with trivial details; (3) colour developing must be carried out under anhydrous condition, thereby water sample palpus evaporate to dryness, and velocity of evaporation and evaporating moisture strict conformance, otherwise causes than mistake.
Three, utility model content
The utility model purpose: simplify the boron testing procedure, shorten minute greatly, alleviate intensity of workers, make a kind of easy to carry, boron colorimetric test tube of using simple and fast.
The technical scheme that the utility model adopted:
A kind of boron 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 the kapillary and the transition section of end sealing, and boron 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
1: H
2=1: 2～20.
Boron 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
1: H
2=1: 11～15.
Described boron colorimetric test tube is represented with unit volume, contains 0.0001% stilbene helianthic acid salt 5～30 unit volumes, pH regulator agent 10～50 unit volumes, mixed preparing forms, and measures the rising or the reduction of each constituent concentration in the liquid, and its volume is corresponding to be dwindled or increase.
Positive beneficial effect of the present utility model:
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 testing 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 boron content more accurately 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, form permanent colour code standard, encapsulation forms the contrast color range, carries out the scene detection 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, also can be, or the colored printing cardboard, or the colored plastic rod by the computer color atlas, and cross other physical medium material such as stained glass goods and form, use very convenient.
3. compare with the method for traditional curcumin spectrphotometric method for measuring boron content, and the utility model does not exist Ca, Mg, NO because of containing in the water quality
3 -And the interference that produces has reduced measuring process, has accelerated finding speed.
4. to measure the chromogenic reaction of liquid and determinand boron 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 sewage comprehensive emission standard.
The utility model carry, easy to use, measure simple, fast, accurately.The on-the-spot detection do not need the miscellaneous equipment instrument, saves human and material resources greatly and reduces integrated cost.The utility model is easy to promotion and implementation, has good social and economic benefit.
