Chemical pre-treatments of oil palm frond for improvement in the removal of zn and cu from wastewater by sorption process

As a result of industrialization, Environmental pollution is becoming more and more serious. Heavy metals are often present industrial wastewaters and need to be removed before discharge. Adsorption is a commonly used method for heavy metal removal from aqueous solutions. Despite of the good efficie...
