Abstract

This paper is to identify lead content in soil by extraction-photometric method and using non-polar solvents (CHCl3) to extract complex of lead (II) -dithizone. The optimal conditions of extraction process of lead(II) dithizonate have been identified: pH is from 8.5 to 10,0; the maximum wavelength of lead(II) dithizonate  compound is 520nm (λmax = 520 nm); absorbance of the solution in compliance with the Bougher-Lambert-Beer law is in wide range from 0.02 to 0.1 mg/l.
