Dynamic loop microwave auxiliary clear-up device

Abstract

The invention relates to a dynamic circulation microwave auxiliary digestion instrument, which is composed of a microwave source (1), a microwave resonant chamber (2), a peristaltic pump (3), an accumulator (4) and a test solution pipe (5), wherein the peristaltic pump (3) pumps the test solution in the accumulator (4) into the test solution pipe (5) which has a coil pipe structure (23) in the microwave resonant chamber (2), the test solution in the coil pipe (23) is digested via coupled microwave and flows back to the accumulator (4). The invention has the advantages that the invention can significantly accelerate digestion reaction which is hard to process at normal temperature or needs long reaction time, as the digestion reaction of COD content test in waste water. The COD digestion of national standard method needs 2h at high temperature, while the inventive method only needs several minutes. The invention can be combined with checker or analysis technique, with better extension and wide application.

Description

technical field [0001] The invention relates to a dynamic circulation microwave-assisted digestion device, which has the characteristics of fast and high efficiency and can be widely used in analysis and testing work in the fields of food, chemical industry, pharmacy, environment and the like. Background technique [0002] At present, in the analysis and testing work in the fields of food, chemical industry, pharmaceuticals, environment, etc., there are many digestion reactions that are difficult to carry out at room temperature or have a long reaction time and high reaction temperature, which greatly prolongs the analysis and testing time and affects work efficiency. , while inevitably consuming a large amount of reagents and producing a large amount of environmental pollutants. Therefore, it is very important to design and manufacture an analytical device that can accelerate the digestion reaction, reduce reagent consumption, and use mild reaction conditions. [0003] Mic...
