Abstract
This study evaluates the effectiveness of three physico-chemical processes in treating acidic soil leachate. Chemical precipitation was tested using calcium hydroxide and sodium hydroxide, and electrocoagulation was evaluated via an electrolytic cell using mild steel electrodes, whereas sorption process was tested using cocoa shells as sorbent. Chemical precipitation was as effective as electrocoagulation in reducing both metals (Pb and Zn) under the permissive level (2.0 and 10 mg l –1 respectively), more than 97% of each metal was removed. By comparison, the sorption process using cocoa shells allowed reaching 90% of Pb removal, while the process removed 92% of Zn.
