| ABSTRACT Electron beam irradiation is an important technique for removing heavy metal ions from their solutions especially of high concentrations. Humic acid is used as organic scavengers HO● radical to prevent metals from reoxidation and reduce the energy used. The adsorption experiments were carried out on model solutions containing two metals: Cr6+ and Cs+. The removal technique was carried out by irradiation and adsorption using humic acid. The adsorption technique was affected by several factors such as equilibration time, solution pH, conc. of chromium ions and humic acid. Different irradiation doses 25 – 150 KGy, and different concentrations of Cr6+ and Co2+ ions were used. The removal percentage was almost 100% in the presence of humic acid during irradiation with low dose 25 kGy. | ||||
