Adsorptive Removal of Some Heavy Metals from Aqueous Solutions by (Hyphaene Thebaica) Charcoal

Abstract

The aim of the present study was to study the adsorption of the heavy metals (copper, zinc, lead and cadmium) usingHyphaeceneThedaica(Doum). Doum palm charcoal was made by ignition of Doum palm into airtight metal tray slot for four hours, then the Doum palm charcoal was soak in different solution of heavy metal salts for half an hour. Atomic absorption Spectroscopic Technique wasused to measure the heavy metals concentrations in their solution before and after addition of Doum charcoal. The atomic analyses showed that the Doum charcoal is a good adsorber of the metal Ion in samples. The heavy metals concentrations of (copper, zinc, lead and cadmium) was decreased after Doum charcoal was added (copper: from 78.8 ppm to 7.34 ppm, zinc: from 40.11 ppm to 19.76 ppm, lead: from15.28 ppm to 5.71 ppm, cadmium: from38.32 ppm to 0.88 ppm).
