日本神户制钢所开发成功可高效率吸附和净化砷(As)元素的铁粉,并将推出相应的商品。该铁粉以净化工厂污水、温泉废水以及地下水等为目的,只需让受到砷污染的水连续流过装有铁粉的容器,即可将砷浓度降至环境标准值(饮用水标准值)0.01mg/L以下。与以前的砷吸附剂相比,具有其2倍以上的吸附力。不仅可用于砷,还可用于铅(Pb)、镉Cd)以及硒(Se)等重金属的净化。
Japan’s Kobe Steel developed a successful high-efficiency adsorption and purification of arsenic (As) elements of iron powder, and will launch the appropriate commodity. The purpose of this iron powder is to purify factory effluents, hot spring wastewater, groundwater, etc. The arsenic concentration can be reduced to the environmental standard value (drinking water standard value) by continuously passing arsenic-contaminated water through a vessel containing iron powder, 0.01mg / L or less. Compared with the previous arsenic adsorbents, it has more than twice as much adsorptivity. Not only for arsenic, but also for lead (Pb), cadmium Cd) and selenium (Se) and other heavy metals purification.
