EFFECT OF PENTAAMMINECOB ALT (III) COMPLEXES OF D- AMINO ACIDS ON THE LEATHER TANNERY EFFLUENTSA. THAMINUM ANSARI AND K. SUBRAMANI
Cobalt (III) complexes of a-amino acids are studied as coagulants for tannery effluent. The effect of these complexes have been studied as a function of various experimental parameters such as pH, chloride concentrations, BOD, COD, TS, TDS, inorganic and organic dissolved salts. The effect of these coagulants were also studied in relation to the various pollution causing parameters. The experimental results were compared with those obtained using ferric alum. was carried using a Jar test procedure in 2L. beaker with 1L. sample. The sample was agitated for 15min. at 20 rpm and siphoned off after 2hr. settling without disturbing the sludge interface. The optimum dosage
