Abstract

The full-automatic chemical oxygen demand analyzer comprises a digestion module, a condensation module, a lower liquid adding module, an upper liquid adding module, a stirring module and a titration module, and digestion, condensation, liquid adding, stirring and titration of a sample are automatically achieved. According to the full-automatic chemical oxygen demand analyzer based on the dichromate method, provided by the invention, full-automatic detection of CODCr is realized, the detection condition is stable, and the applicability is high.

Description

technical field [0001] The invention relates to the technical field of chemical analysis and detection equipment, in particular to a fully automatic chemical oxygen demand analyzer based on a dichromate method. Background technique [0002] The chemical oxygen demand of dichromate method, referred to as CODCr, is to measure the amount of reducing substances that need to be oxidized in water, and is an important indicator to reflect the degree of water pollution. CODCr in water is too high, indicating serious organic pollution, so it is also an important parameter in the fields of environmental testing, wastewater treatment, etc. 2017). [0003] The CODCr detection operation process is complicated, and many reagents are used, and the reagents are corrosive and toxic. The detection process is extremely sensitive to conditions. However, there are many problems in the current CODCr detection equipment on the market, such as the detection process still relies on manual operation...
