Abstract

A novel approach for the removal of heavy metals from aqueous solutions was carried out using agricultural adsorbent (palm kernel shell charcoal) and UV-visible detection. This technique was applied for the recovery of cadmium (Cd), chromium (Cr) and copper (Cu) species. Percentage recoveries for cadmium at buffer 0.1M ranged from 98.01-98.63% while at buffer 0.2 M the percentage recovery of cadmium ranged from 99.15-99.42%. For chromium the percentage recovery at buffer 0.1 M ranged from 98.83-99.48% while at a buffer of 0.2 M the percentage recovery of chromium ranged from 99.01-99.18%. For copper adsorption the percentage recovery at buffer 0.1 M ranged from 99.62-99.91% and at buffer 0.2 M the percentage recovery ranged from 99.32-99.98%. Copper recovery was higher at buffer 0.1 M than at buffer 0.2 M, while chromium and cadmium had higher recovery rates at buffer 0.2 M. This is plausibly due to the higher ionic strength of Cu compared to Cd and Cr. The method can be used to conveniently remove Cd, Cr and Cu in aqueous media.
