- Abstract
Background: The development of a method for determining Cd is relevant for solving problems of environmental protection, diagnosis of diseases, and food quality Purpose: to develop a cheap, fast and hybrid method for the determination of Cd ion. Methodology: absorption, reflection and SEM spectra of the complex compound obtained during the determination of Cd ion were studied . Originality: Cd(II) ion Development of a sorption-spectrophotometric method for the determination of 4-nitro-2-arsenobenzene-1,4 diazominoazobenzene-4 sulfo acid using monosodium salt . Findings: optimum formation of complex with organic reagent used for determination of Cd ion light absorption, light reflection and SEM analysis methods were used to determine the conditions.
