Nickel Online Water Quality Analyzer
>>Overview
>>Principle
The product employs the spectrophotometric method for nickel detection. After mixing the water sample with a buffer agent, nickel is oxidized to higher oxidation states using a strong oxidizing agent. In the presence of a buffer solution and indicator, the oxidized nickel ions react with the indicator to form a colored complex. The monitor detects this color intensity change at specific wavelengths, converts it into nickel concentration values, and outputs the results. The amount of colored complex generated corresponds to the total nickel concentration.
