Five millilitre of the solution was taken after the equilibration time then filtered off,
where the residual concentration of metal ion was determined via the titration against 5 · 10\23 M EDTA using PAR as indicator for Hg(II),murexide for Cu(II) and EBT for Ca(II),Mg(II),Cd(II),Zn(II) and Pb(II).The estimation of Hg(II) in a binary mixtures of Cu(II),Cd(II) and Zn(II) has been carried out according to the above procedures using KI as a masking agent for Hg(II)
