Nickel removal from electroplating waste water using stand-alone and electrically assisted ion exchange processes
Ismail, I.; Soliman, A.; Abdel-Monem, N.; Ahmed, H. Salah & Sorour, M. H.
Abstract
Wastewater discharged from metal-finishing
processes usually contains nickel, a hazardous substance
that is used extensively in the surface finishing industry. In
the present study, an acidic solution containing nickel was
treated using strong acid cation exchange resin. A continuous
lab-scale cation exchange arrangement permitting the
assessment of electric current as an enhancement mechanism
was designed and utilized at different flow rates
successfully. Applying the electrical potential enhanced the
nickel removal by 12.7 % at flow rate 240 ml/h, and 2.5 %
at flow rate 500 ml/h. Nickel recovery has been also
investigated using hydrochloric acid as an eluent with and
without electric current enhancement.
