CHEMetrics Zinc Test Kit
Zinc deposits are present in much of the earth’s crust. The metal provides an effective protective coating for steel (galvanized coatings) and is useful as an alloying agent. Zinc salts are useful as corrosion inhibitors in cooling water treatment formulations. The USEPA has established a Maximum Secondary Drinking Water Standard of 5 mg/L for zinc.
Requires the use of a photometer or spectrophotometer.
