Abstract
Phoenix dactylifera L. date palm fruits are consumed largely worldwide. The date stone wastes from the date processing industries are huge and needs attention due to their high lignocellulose content. It is one of the good precursors for activated carbon and can be utilized for heavy metal remediation from wastewaters. Therefore, this chapter reports the metal ions adsorption by activated carbons prepared from date stone considering recent works of literature. This review elaborates the activation methods employed for activated carbon preparation, characterization strategies, parameters affecting the adsorption experiments and adsorption efficiency of the prepared carbons.
