Problems solved by technology

[0003] The traditional dilution method for high-concentration water samples is usually manually operated by adding distilled water to a quantitative high-concentration water sample so that the volume of the mixed solution obtained at the end is a multiple of the volume of the quantitative high-concentration water sample, and then the mixed solution is passed through Stir or shake to make it evenly stirred, let it stand, and finally take a quantitative diluted high-concentration water sample for direct measurement to obtain the analysis results. The entire dilution process is cumbersome and time-consuming, and wastes reagents

Embodiment Construction

[0014] Such as figure 1 As shown, set the position of the light source and sensor on the optical quantitative device to x1, the position of x1 is the position where the amount of high-concentration solution to be pumped reaches in the container; set the position of another pair of light source and sensor to x3, x3 The volume of the container is 3 times that at x1. After the setting is completed, draw a high-concentration solution into the optical quantitative device through a channel of the multi-channel block set under the optical quantitative device, and when the high-concentration solution reaches x1, close the channel; then, set it under the optical quantitative device Another channel of the lower multi-channel block draws the diluent into the optical quantitative device, and when the diluent reaches x3, the channel is closed; finally, after the optical quantitative device is left for 1-2 minutes, the liquid in the optical quantitative device It is the solution that can b...

Abstract

The invention discloses a method and equipment for diluting high-concentration solution to be tested in a dynamic flow way, which are applicable in the field of industrial analysis; when diluent is extracted, a water sample with high concentration and distilled water are mixed in a dynamic flow way, the volume of the mixture is small, so the mixture is uniformly mixed very quickly after staying still for a while; the diluted mixture is injected into a reactor for reaction measurement; and the hole process takes a short time, has no reagent waste, dilutes precisely and has good repeatability. The invention can automatically dilute the high-concentration water sample with high efficiency, can be integrated with a microprocessor in the industrial production, sets time, regularly extracts, and saves the trouble of manual operation.

Description

technical field [0001] The invention relates to a wastewater detection method, in particular to a method suitable for dynamic flow dilution of a high-concentration test solution in the field of industrial analysis. Background technique [0002] At present, in the field of industrial analysis, the analysis of liquids, such as the analysis of water quality, accounts for a considerable proportion. In water quality analysis, the analysis of high-concentration water samples of water quality indicators is particularly important. However, due to cost and technical limitations, it is not possible to directly measure high-concentration water samples of water quality indicators at present. To analyze high-concentration water samples of water quality indicators, the high-concentration water samples of water quality indicators must first be diluted to make the high-concentration water samples Concentrated water samples are converted into low-concentrated water samples, and then analyze...
