Description
The present invention relates to a kind of water examination method and apparatus, specifically, it is rapid analysis and the equipment that is applicable to the on-the-spot quick test case use of rural potable water, rivers and lakes water.
Existing water analysis method need use specialized equipment to carry out in the assay laboratory, can not adapt to the needs of the on-the-spot quick test of rural potable water and rivers and lakes water.At present existing some on-the-spot method for quickly detecting, but its sensitivity accuracy is all not good enough, is only applicable to the detection of the higher high salinity water sample of some content, still inapplicable for the water sample that salinity is lower, and do not set up the method for quickly detecting of manganese as yet.Be applicable to the visual colorimetric determination device complex structure of this fast detecting case adapted, the cuvette of use is 2 centimetres, and insufficient sensitivity also need carry distilled water, has both increased weight, has put for a long time also and can go bad.
The objective of the invention is to the rapid analysis and the equipment of the on-the-spot fast measuring tank of water quality are improved, the sensitivity of raising method, accuracy adapting to the needs of various water examinations, and make device structure simpler, use more conveniently, and weight is lighter.
The object of the present invention is achieved like this: the rapid assay methods of at first having set up manganese; Replaced existing method with some sensitivity, the higher method of accuracy again; And the visual colorimetric determination device done improvement, make sensitivity, accuracy higher; Also develop a kind of minitype ion exchange water purifior, overcome the defective that need carry distilled water.
The rapid assay methods of the manganese that the present invention sets up is to utilize under alkalescence and pyrophosphate existence condition, with potassium metaperiodate low price manganese is oxidized to the high price manganate, and specific procedure is as follows: following reagent is even by following percentage mix:
Potassium pyrophosphate 68 anhydrous sodium acetates 20 potassium metaperiodates 4
Potassium nitrate 5 potassium pyrosulfates 3
And careful the grinding, cross the 60-100 mesh sieve then, place in the little reagent bottle, and put on manganese mark " Mn ".
During mensuration, in the 25ml color comparison tube, add water sample, add one spoonful of reagent " Mn " (0.1 gram), shake up dissolving, placed 30 minutes, with 10 centimetres of cuvette visual colorimetric determinations to 25ml.
Other improved methods have:
The mensuration of fluoride selects for use the fluorine reagent method to replace the alizarin sulfonic acid zirconium method of fading, and more former method color range changes obviously, and disturbing factor is few, stable reagent.
The mensuration of surplus nitrogen selects for use the DPD method to replace diaminoditolyl method, this law favorable reproducibility.
The mensuration of total iron replaces the dipyridine colourimetry with the phenanthroline colourimetry, and sensitivity improves.
The mensuration of PH: the color range sheet of making in its PH color change interval with acid base indicator carries out colorimetric estimation replacement PH test paper method, has overcome the PH test paper and has been subjected to CO in the air
2Interference, the shortcoming of poor accuracy.
The mensuration of turbidity adopts the opacity tube direct-reading methods to replace the visual chart method, is about to water sample and adds in the self-control turbidity pipe, observe downwards from the mouth of pipe, " O " that water sample is added at the bottom of the lucky identification pipe number exceeds, and direct reading from the turbidity pipe scale has overcome the ocular vision error then.
The mensuration of sulfate replaces tetrahydroxy ketone sodium salt method with barium sulfate turbidimetry, and sensitivity improves.
Estimating Total Hardness changes borate buffer solution into the ammonia buffering agent, makes terminal point clearer.
The required reagent of above method is mixed by stoichiometry, the careful grinding, and by the 60-100 mesh sieve, be respectively charged into little reagent bottle, and put on the sign of this mensuration project.Get certain water sample during mensuration by the little spoon adding required reagent of required amount of reagent, shake up, dissolve, place certain hour and carry out visual colorimetric determination with quantitative every spoonful 0.1 gram.
The used visual colorimetric determination device of above colorimetric analysis is improved.The body of colour comparator of the present invention is one can place the cell of 3 cuvettes, and its front end is provided with hole and 3 socket grooves that can insert standard color range sheet of three energy printing opacities; The baffle plate that end has a transparent material to make is made view window; Path length 100-120 millimeter in three cuvette grooves, can place 2-10 centimetre of cuvette, use 10 centimetres of cuvette sensitivity to improve 5 times than 2 centimetres of cuvettes, the color range sheet is to be embedded on the transparent material with the segmentation of 2-4 the organic color range diaphragm of standard, form with the transparent material sealing again, all the color range sheet can be placed in a little color range sheet underedge, and puts on corresponding mensuration project and concentration.
Fig. 1 is a visual colorimetric determination device synoptic diagram of the present invention
Fig. 2 is a color range sheet synoptic diagram of the present invention
Wherein [1], [2], [3] are three cuvette grooves, and [4], [5], [6] are the hole of three printing opacities, and [7], [8], [9] are the color range film trap, and [10], [11], [12] are view window, and [13] are the cell lid, and [14] are the color range sheet.
During mensuration, water sample to be measured can be pressed in the routine analyzer colour developing back impouring cuvette, cuvette groove [2] in the middle of placing, and in corresponding color range film trap [8], insert blank color range sheet, with not adding reagent, blank water sample adds in the cuvette again, place cuvette groove [1], [3] on two limits respectively, two color range sheets are inserted in corresponding color range film trap [7], [9], cover cell lid [13], visual colorimetric determination from view window [10], [11], [12].See that the color of colour developing back water sample and any color of color range sheet are similar to, the pairing concentration of this color range sheet is the content of the project of surveying in the water sample.
By above improved analytical approach and equipment, sensitivity, the accuracy of the rapid analysis of the on-the-spot fast measuring tank of water quality are all reached or the requirement of the analytical approach that is near the mark, and the needs of applicable various water examinations, and equipment is easy to use, in light weight, easy to carry.
