The System Overview of the Total Manganese On-line Analyzer presents a cutting-edge automatic monitoring system developed based on the Chinese environmental protection industry standard method HJ/T344-2007. This advanced Instrument is part of a comprehensive series of water quality analysis products, designed for long-term, maintenance-free operation in real-time monitoring applications.
Once a pre-treated water sample is introduced into a specialized reactor via a syringe pump, it undergoes a multi-step chemical process. First, a reducing reagent is added to convert all manganese species present in the sample into divalent manganese ions (Mn²âº). Following this, the pH of the solution is adjusted to optimize reaction conditions. Finally, a specific chromogenic reagent is introduced, triggering a color development reaction.
The intensity of the resulting color change is directly proportional to the concentration of total manganese in the sample within the designated measurement range. By continuously measuring the absorbance or color intensity using a spectrophotometric sensor, the system accurately calculates and displays the total manganese content in real time. This makes the analyzer ideal for continuous monitoring in industrial wastewater treatment plants, municipal water systems, and environmental surveillance programs. Its reliability, accuracy, and low maintenance requirements make it a preferred choice for modern water quality management.
