Fluoride removal by Palm Kernel Shell Activated Carbon (PKSAC): batch and isotherms approach

Fluoride, which is classified as one of the contaminant of water for human consumption by the World Health Organisation (WHO) has been recognised as one of the serious problem worldwide by contaminating the groundwater. According to WHO, the standard prescribed for fluo1ide ion concentration in drin...
