Abstract
The utility model provides a chromium in-water fast testing kit. A kit body is a hollow body with a concave chamber in the middle. One edge of a kit cover is connected with the upper edge of the kit body in an integration type and other edges thereof are connected with the upper edge of the kit body in a fastening way; a reagent bottle and a glass colorimetric tube used for the storage of liquid reagent is arranged in the kit body with moderate tightness; colorimetric cards with a series of standard colour gradation is inserted and connected between the internal wall of the reagent bottle or the colorimetric tube and the kit body. The utility model fabricates the colorimetric cards according to standard solution, tests the chromium in water by using visual colorimetry, adopts a liquid agent for all agents, simplifies operation steps, improves testing sensitiveness, overcomes the shortage of low testing sensitiveness of the visual colorimetry and obtains exact testing results. The utility model has the advantages of simple operation, convenient storage and transportation and being suitable for fast testing in-site, etc.
Description
Technical field
The utility model relates to the water quality monitoring technical field, chromium fast measuring kit in higher, the simple and rapid visual colorimetry water of especially a kind of sensitivity.
Background technology
Chromium is a kind of important environmental contaminants, has very high toxicity and carcinogenesis.Chromium in the water body is mainly from industrial waste waters such as plating, process hides, weaving, dyestuff, metallurgy, chemical industry.At present, the assay method of chromium mainly contains in the water quality monitoring:
(1) spectrophotometric method, commonly used have a diphenyl carbazide spectrophotometry etc.Though these methods can obtain accurate result, formality is loaded down with trivial details, needs to adopt spectrophotometer to measure, and operating personnel's professional skill is required height, can only finish in the laboratory;
(2) titrimetry, commonly used have a ferrous ammonium sulfate titration.Though these class methods are easy and simple to handle, the sensitivity of measuring is lower, only can measure the water sample of chromium content more than 1mg/L.
(3) atomic absorption spectrophotometry, this method can be measured the chromium of low concentration in the day water and the industrial waste water, and measurement range needs to adopt flame atomic absorption spectrophotometer to carry out at 0.3～10mg/L but measure, and instrument costs an arm and a leg, and cost of determination is higher.
In sum, when more than Chang Yong chromium assay method is used for the field monitoring of water body chromium, all there is such or such weak point, is difficult to satisfy the rapid sensitive of chromium, the actual requirement of on-site measurement.
The utility model content
The purpose of this utility model provides a kind of highly sensitive, and is easy and simple to handle, chromium fast measuring kit in the water of suitable fast-field evaluation.
The purpose of this utility model reaches by following technical measures: chromium fast measuring kit in a kind of water, have box body and lid, box body is that a centre is the ducted body of cavity, one side of lid is in one-piece connection with the box body upper edge, other several limits are connected with box body upper edge fastening formula, degree of tightness moderately is provided with the reagent bottle and the glass color comparison tube of contain fluid reagent in box body, the colorimetric card that setting has the series of standards color range that links to each other of pegging graft between reagent bottle or color comparison tube and the inboard wall of cartridge.
Be provided with the reagent bottle that three volumes are 50mL in the described box body, the bottle cap of each reagent bottle top configuration all indicates the 1mL scale mark, and bottle cap all can be used as the reagent sampler and uses; It is teflon that reagent bottle prepares material.
The pipe diameter of described glass color comparison tube is 2～3cm, highly is 10～15cm, and the color comparison tube middle part indicates the scale mark of 5～10mL.
The utility model is made colorimetric card according to standard solution, adopt visual colorimetry to measure chromium (VI) in the water body, agents useful for same is liquid dosage form, simplified operation steps, because adopting DApHVM is developer, improve the sensitivity of measuring, overcome visual colorimetry and measured the lower shortcoming of sensitivity, can obtain measurement result accurately.That this utility model has is easy and simple to handle, be convenient to accumulating, is fit to advantages such as fast-field evaluation.

Referring to Fig. 1～shown in Figure 4, chromium fast measuring kit in a kind of water is made up of color comparison tube 1, reagent bottle 2, colorimetric card 3, and suit wraps in the packing box and constitutes.
In packing box, be provided with three bottles of reagent bottles 2 that are loaded with liquid reagent, be loaded with 95%H in the reagent bottle respectively
3PO
4Liquid reagent, 12.0g/L MnSO
4Liquid reagent and 0.5%DApHVM liquid reagent.
Survey chromium colorimetric card 3 and have two, one have 0.05,0.1,0.2,0.4,0.6,0.8,1.0,1.2, nine circular standard color ranges of 1.4mg/L, another has 1.5,1.6,1.8,2.0,2.2,2.4,2.6,2.8, nine circular standard color ranges of 3.0mg/L.The making of standard color range is relevant regulations preparation chromium (VI) standard serial solution according to GB/T 14962-94, it is 2～3cm that standard solution and three kinds of each 1mL of liquid reagent of the present utility model are mixed to diameter, highly be in the cylindrical glass color comparison tube of 10～15cm, according to shown color, adopt electric point-score production standard color range colorimetric card.
With in this kit measurement water during chromium concn, earlier water sample to be measured is filled to the scale mark of color comparison tube, add three each 1mL of the reagent in the reagent bottle respectively, cover the vinyl cover of color comparison tube, after shaking evenly, placing five minutes, color comparison tube is carried to from the about 2 centimetres of eminences of colorimetric card and standard color range visual colorimetric determination from top to bottom, is exactly the concentration (mg/L) of chromium in the water sample with the color range that the solution tone is identical in the pipe.
