Measurement principle

Nickel ions are first oxidized to tetravalent in ammonia or alkaline solutions, and then react with colorants to form complexes. Their absorbance is then measured by spectrophotometry, and the nickel content (mg/L) is directly displayed after processing and calculation by a microcomputer system.
