Problems solved by technology

However, the detector needs to be tested under alkaline conditions. Precipitation of hydroxide and manganese dioxide in the solution leads to inhomogeneous solution, serious light scattering, and contamination of detectors and pipelines, resulting in large detection errors and instability. Directly affect the accuracy and precision of seawater COD detection; the instrument uses cold light source photometric titration to judge the titration end point, which increases the detection cycle of the instrument, slow detection speed and low efficiency
