Product principle:

The water sample is digested to convert various valence states of cadmium into divalent cadmium ions. Under alkaline conditions, cadmium ions react with specific color reagents to form stable colored complexes. The absorbance of the complexes is detected by the principle of photoelectric colorimetry, which is used to convert the concentration of cadmium.
