Description

The objective of this study is the adsorption of chromium on activated carbon produced from agri-food waste such as the shells of Balanites aegyptiaca (L.) Del. (Adoua), Hyphaene thebaica (L.) Mart. (Gorouba), Zizyphusmauritiana (L.) Lam. (Magaria) and Balanites aegyptiaca (L.) Del. cake by chemical activation with 25% orthophosphoric acid and 25% sulfuric acid. The mass yields of the ACs after pyrolysis, surface functions (Boehm method), pH at zero loading point (return dosage) and methylene blue (MB) adsorption capacities are determined.
