Application. of the electron-beam treatment for Ca, Si, P, Al, Fe, Cr, Zn, Co, As, Se, Cd and Hg removal in the simulated and actual industrial effluents

The removal of Ca, Si, P, Al, Fe, Cr, Zn, Co, As, Se, Cd and Hg was determined in the simulated and actual industrial effluents using electron-beam treatment. The actual effluents gave the following results: a removal of ca. 80% for Ca and P with 20 kGy irradiation doses; more than 96% for Al and Si with 100 kGy; more than 99% for Ca, Fe, Zn, Cr and Co with 200 kGy and Fig showed a 71.0% removal with 500 kGy. In the simulated industrial effluent solution, As and Hg showed 92.5% and 99% removal with 500 and 100 kGy irradiation doses, respectively. Se and Cd showed a 99.6% and 44.0% removal with 500 kGy. HCOONa solution was added for Hg and As removal, and irradiation process was done in the oxidant atmosphere. (C) 2004 Published by Elsevier Ltd.
