Four new complexes were prepared by the metathetic reaction of  trace heavy metals like Cd, Zn, Cu and Hg with two different dithioligands of the formula ML₂ [ M= Cd, Zn, Cu & Hg and L= potassium-1,1-dicyano-2,2-ethylenedithiolate and potassium N-4-fluorobenzyl,N butyldithiocarbamate ] and characterized by Elemental Analysis, IR, UV-Visible, ¹H,¹³C NMR and AAS. AAS measurements revealed that  the N- substituted dithiocarbamate ligand are more effective removal efficiency of heavy metals than C- substituted dithiocarbamate ligand . Molar Ratio studies show that the complexes have the formula ML₂. Solvent extraction measurement indicates that after the extraction of heavy metal in water phase and their dithiocarbamate complexes are completely dissolved in organic phase and are totally separated from water solution.
