Abstract

Cocoa shell pellets were converted into activated carbon (CSAC) by carbonization at 800 degrees C followed by activation at 850 degrees C in CO2 flow until reaching burn off at approximately 48%. The CSAC was treated with hydrochloric acid (HCl) using response surface methodology (RSM), where the effect of soaking times (1, 2 and 4 h), temperatures (30, 50, 70 degrees C) and concentration of HCl (0.1, 1 and 2 M) were studied. CSAC treated with 1 M HCl at higher temperatures (>60 degrees C) yielded CSAC with low ash content (
