Clean fresh water resources are getting harder to find every single day. Since the life on Earth depends on water, it is crucial for humankind to find easier, faster and cheaper solutions to purify water. Industrial wastewaters should be treated appropriately. Governments are getting more serious about this issue by publishing regulations based on research about the health effects of heavy metal contaminations. Hence, removing contaminants is becoming to be bigger priority. In this study, corn stalk (CS) is used to produce adsorbent materials to remove heavy metals from wastewater. As heavy metals; Pb2+, Zn2+, Ni2+, Cd4+, Cr6+, Cu2+, Al3+ and Mn2+ were selected due to their high abundance over the industrial waste waters [1]. Heavy metals have harmful effects on human body. For example, lead that exposed into the human body, is stored temporary in bones, blood and tissues [2]. Repeatedly exposure to lead at a high level can cause anaemia, reproductive impacts, kidney failure, and effects upon the peripheral and central nervous system that include convulsions, coma, and death [3]. Therefore, according to World Health Organization, the lead concentration in the industrial wastewater discharge must be 0.01 mg/L at its maximum [4]. The aim of this project is to find an easy, cheap and quick way of removing selected heavy metals
