If other anions and metal cations are present in the methylene blue solution after the reaction is complete, how can they be detected? If instruments such as ICP or IC are used, organic substances must not be present in the solution; then can the methylene blue solution be treated to remove the organic compounds before using the instrument for analysis?

Multi-parameter water quality analysis instruments can quickly and accurately determine various parameters in surface water, groundwater, urban wastewater, and industrial waste water, including residual chlorine, total chlorine, combined chlorine, chlorine dioxide, dissolved oxygen, ammonia nitrogen, nitrite, chromium, iron, manganese, color, turbidity, suspended solids, etc., with the concentrations displayed directly. Anions and metal cations in methylene solutions can also be directly measured using a multi-parameter water quality analyzer.
