Analytical Applications of DEAPG as Gravimetric Reagent-I Estimation of Hg(II)

Chemistry Department, N.R.E.C. College, Khurja (U.P.) Manuscript received 12 October 1979, accepted 30 December 1979 p-Diethylaminoanil of phenyl glyoxal (abbreviated as DEAPG) precipitates Mercury(II) quantitatively and gives dark brown complex at pH 9.8 by adding double theoretical quantity of the ligand. It can be used for the gravimetric estimation of Hg(ll) either alone or in presence of foreign ions
