Activated carbons

In recent years, the increasing level of underground water shows a high iron and manganese concentrations, thus, the technology of water treatment requires application of processes for Fe and Mn removal. Within a literature, many treatment processes have been proposed for manganese removal from drin

Three activated carbons have been prepared from dates stones, by carbonization without adjuvant and by chemical activation with ZnCl2 and KOH. According to the nature of the adjuvant, the activated carbons present different porosities. Chemical activation of the date stones with KOH produces an acti
