contaminating the river and the ground water as well. To fix a solution
for this issue a simple and selective solvent extraction method has been applied by using a
newly synthesized quaternary ammonium salt viz 2-benzoylethylheptyldimethylammonium bromide.
By varying the parameters such as quaternary ammonium salts, sulfuric acid, pH, solvents,
equilibration time and aqueous organic ratio the extraction efficiency has been determined.
