Removal of lead (II) ions from aqueous solution using desiccated coconut waste as low-cost adsorbent

Waste from coconut milk processing industry namely desiccated coconut waste (DCW) was used to remove Pb (II) due to Pb (II) hazardous effect in the environment. The main objective of this study is to study and develop the adsorption capability of the DCW adsorbent. The chemical and physical properti...
