Organic matter in water enriching concentrating instrument and control method thereof

Abstract

The invention relates to an enrichment concentrator and an extraction method of the organic matters in water, the instrument includes: a reagent bottle, a separatory funnel, a glass three-way connector, an anhydrous sodium sulfate dehydration column, a KD concentrator, a heater, a water sample bottle, an electromagnetic stirrer, a pipe of a connecting gas path or a water path, an activated carbon column, a nitrogen bottle, an electromagnetic valve and a single-chip microcomputer automated control system. The enrichment concentration extraction method of the organic matters in water takes the liquid-liquid extraction and KD concentration in the methods recommended by international standards (ISO6468) and the state as the basic working principle and carries out the optimization and integration of all the steps of the complicated entire manual liquid-liquid extraction and KD concentration, the invention can carry out the continuous work, automatically process the sample pretreatment, improve the working efficiency of the experiment, reduce the secondary pollution of the sample processing on the environment and protect the body health of the working staff, so the invention can be widely applied in the monitoring departments and research institutions of the water quality of the waste water and the drinking water.

Description

Technical field [0001] The invention belongs to an environmental monitoring and water quality analysis instrument. It is used for the enrichment and concentration of organic matter in water, and integrates and automatically controls the pretreatment of water samples for the analysis of most organic matter in gas chromatography and GC-MS. Set concentrator and control method. Background technique [0002] At present, whether it is the needs of industrial development or the needs brought about by the improvement of people's living standards, the related fields are paying more attention to the organic matter in wastewater, especially drinking water. This is because certain organic matter in water is often the main cause. Distorted, carcinogenic, and mutagenic compounds are harmful to human health. In the newly promulgated "Sanitary Standards for Drinking Water" (GB5749-2006), China has added more than 60 organic indicators, which indicates that more arduous tasks and higher requireme...

AI Technical Summary

Problems solved by technology

[0008] 1. The existing two products only solve the problem of high labor intensity in the enrichment process

[0009] 2. Changing manual shaking to mechanical or jet shaking is a transformation of the single enrichment or extraction process, and does not involve the concentration process

[0010] 3. The method of jet vibration does not adopt the international or national standard method, which makes it difficult to compare the analysis results with other analysis results of the same type
