Detailed Product Description

Hexavalent Chromium Online Water Quality Analyzer

 

>>Overview

The toxicity of chromium correlates with its oxidation state, with ‌hexavalent chromium (Cr⁶⁺)‌ being approximately ‌100 times more toxic than trivalent chromium (Cr³⁺)‌. Cr⁶⁺ is more readily absorbed and accumulates in the human body, increasing the risk of liver cancer. Consequently, China has classified hexavalent chromium as a key pollutant subject to total emission control.This monitor operates autonomously under ‌long-term unattended continuous operation‌ based on field configurations. It is widely applicable to industrial wastewater discharge, process wastewater, industrial and municipal sewage treatment plants, and similar environments. Depending on on-site complexity, optional preprocessing systems can be integrated to ensure ‌reliable testing processes‌, ‌accurate results‌, and compliance with diverse operational demands

 

>>Principle

The product utilizes the ‌diphenylcarbazide spectrophotometric method‌ for hexavalent chromium detection. After mixing the water sample with conditioning agents, Cr⁶⁺ reacts with the indicator in an acidic environment to form a colored complex. The monitor detects the color intensity change at specific wavelengths, converts it into Cr⁶⁺ concentration values, and outputs the results. The amount of colored complex generated is proportional to the hexavalent chromium concentration.
