Adsorption Study Of Heavy Metals And Natural Organic Matters (Nom) In Groundwater Using Metakaolin

Groundwater is an increasingly important source of water due to lack of surface water supply that caused by climates vagaries and declined surface water quality. However, prior to consumption, it is very essential to recognize the quality of groundwater to avoid adverse effect to health as the qu...
