In the present study, the biosorption behavior of rice straws biochar beads was investigated for strontium removal from wastewater bodies. Strontium occurs naturally at the average amount of 0.04% and is considered the 15th most abundant element of earth’s crust. It is recognized as one of the environmentally hazardous constituents and acts as a major pollutant in nuclear water discharges. It is widely used in electronics, pharmaceutical, pyrotechnics, and metallurgical industries that release strontium-rich watewater. Therefore, it is vital to remove it from the wastewater bodies. The biosorption process was carried out by using beads of rice straws biochar used as biosorbent.
