Determination of Copper concentration in process water
The concentration of copper (0.2-2 mg/L) in galvanic waters indicates that the wastewater is not suitable for direct discharge into surface waters or sewers and requires treatment. For recycling, values <0.2 mg/L are ideal, while 0.2-2 mg/L require intermediate treatment for reuse in washing or processes, reducing costs and environmental impact.
Method
Test principle
The copper content is determined by its reaction with a chromogen which develops a colour change, whose optical intensity measured at 620 nm, is proportional to the copper concentration in the sample analyzed.
Calibration Curve
The calibration curve for the CDR GalvanLab® instrument was created using standard copper solutions. The curve obtained confirmed excellent linearity across the entire concentration range.
