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

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 carboncolumn, 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 environmental monitoring and water quality analysis instruments, which is used for the enrichment and concentration of organic matter in water, and the integrated and automatic control of organic matter enrichment in water for the analysis of most organic matter in gas chromatography and gas chromatography. 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, related fields pay more and more attention to organic matter in wastewater, especially drinking water, because some organic matter in water often acts as the main cause of pollution. Abnormal, carcinogenic and mutagenic compounds are harmful to human health. In the newly promulgated "Drinking Water Hygienic Standard" (GB5749-2006), more than 60 kinds of organic matter indicators have been added, which indicates that more arduo...
