Abstract
Batch tests were
conducted using an electroplating industry effluent that contained 18.0, 18.9,
8.6 and 15.6 ppm of Cr (VI), Ni (II), Cu (II) and Zn (II) respectively. The
work aimed to evaluate the feasibility of using powdered pseudoactivated carbon
(PAC) prepared from agrowastes for the removal of heavy metals from
electroplating effluents. The ability of coconut coir carbon (CCC), sagaun
sawdust carbon (SSC), wheat stem carbon (WSC) and rice husk carbon (RHC) to
remove heavy metals from the effluent was studied. The sorption was in the
order of Ni >Zn > Cu > Cr over a wide range of initial concentration
1-20 mg/l at sorbent dose 1 g/l. The sorption increased with increasing contact
time but the equilibrium was attained in 2 h for Cr, 3 h for Cu, 3.5 h Zn and 4
h for Ni. The order of metal removal capacities for these chemical sorbents
was: RHC > CCC > WSC > SSC. Electroplating effluent showed 4 to 10%
lower removal as compared to synthetic standard solution under similar
conditions.
