The zinc reagent spectrophotometric method is a classic technique for the determination of trace zinc ions, offering advantages such as operational simplicity and low cost.
Zinc reagent serves as an indicator in complexometric titrations and is applicable to the determination of a wide range of metal ions:
Direct Determination: It can be used directly for the determination of ions such as zinc, copper, and mercury.
Indirect Determination: By being coupled with other reagents, it enables the indirect determination of metal ions including calcium, magnesium, iron, manganese, cadmium, lead, cerium, and indium.
Biochemistry: It can be utilized for the determination of zinc in biological samples—such as serum, urine, and hair—thereby aiding in the assessment of an individual’s zinc nutritional status.
