Role of Modification of Natural Zeolite in Removal of Arsenic from Aqueous Solutions

open access: yesActa Chimica Slovenica, 2018
The adsorption of arsenic from aqueous solution onto natural and modified zeolites was investigated. The natural zeolites were modified by ion-exchange (NH4NO3) and addition of aluminum (Al2(SO4)3). The natural and modified zeolites were characterized by
