With the exploitation of uranium-beryllium ore, the waste and wastewater produced have received extensive attention. There are a lot of toxic and harmful substances in uranium-beryllium ore, among which beryllium has not been widely concerned. This paper used hydrochloric acid (HCl) pretreatment activated carbon (H-AC) to study the removal of beryllium from uranium beryllium ore wastewater. This experiment explored the influence of reaction time, reaction temperature, and other conditions on the adsorption effect. It concluded that the adsorption efficiency was 99% when pH = 5, the amount of a...
