Abstract

Reflectance spectra of mercury with diphenylcarbazone as spots on filter paper were measured by a scanning spectroreflectometer. A functional dependence was found between K/S values of the Kubelka-Munk equation and the concentrations of mercury(II) in solution within the range 5-100 p.p.m. Reflectance spectra of Na+, K+, Ca2+, Sr2+, Ba2+, Mg2+, Fe2+ and Cd2+ ions with the reagent show that these ions do not interfere. Pb2+ and Fe3+ do interfere. Cd3+, Fe3+ and Cu2+ and Pb2+ produce characteristic changes in the reflectance spectrum.
