Abstract

This paper describes a sensitive spectrophotometric method for the determination of mercury, based on the flotation of a mercury iodide-brilliant green complex with cyclohexane at pH 5 and dissolution of the complex in acetone. The absorbance of the complex is measured at 625 nm. Beer's law is obeyed from 4-500 mu g/l of mercury. The method is highly sensitive (epsilon = 5.96 x 10(5) l mol(-1) cm(-1)) and selective,as it is free from interferences by almost all cations and anions in the presence of EDTA. Furthermore, a two-level orthogonal array designas a chemometric method has been used for optimization of the variousparameters involved. The method has been successfully applied to paper industry effluents.
