Magnetically Modified Biosorbent for Rapid Beryllium Elimination from the Aqueous Environment

Although both beryllium and its compounds display high toxicity, little attention has been focused on the removal of beryllium from wastewaters. In this research, magnetically modified biochar obtained from poor-quality wheat with two distinct Fe<sub>x</sub>O<sub>y</sub> cont...
