  • IRON MITIGATION ZINC MEASUREMENT
    Publication number: 20240102923
    Abstract: An embodiment provides a method for measuring zinc in an aqueous sample, including: adding an iron chelating agent to the aqueous sample; chelating an amount of iron in the aqueous sample with the iron chelating agent; and measuring the amount of zinc in the aqueous sample by measuring a change in intensity of the absorbance of the iron chelated aqueous sample. Other aspects are described and claimed.
    Type: Application

  • Zinc and copper measurement
    Patent number: 11549884
    Abstract: An embodiment provides a method for measuring zinc and copper in an aqueous sample, including: reducing an aqueous sample containing an amount of zinc and an amount of copper with a reducing agent; buffering the reduced aqueous sample; chelating the amount of copper in the buffered aqueous sample with a copper(I) chelating agent; measuring the amount of copper in the aqueous sample by measuring a first change in intensity of the absorbance of the copper chelated aqueous sample; chelating the amount of zinc in the buffered aqueous sample with a zinc(II) chelating agent; and measuring the amount of zinc in the aqueous sample by measuring a second change in intensity of the absorbance of the zinc chelated aqueous sample. Other aspects are described and claimed.
