制备了大孔和DH302 2种MnO2的负载树脂。并用SEM、EDS手段表征了负载树脂,实验了负载MnO2后树脂对As(V)的去除效果。结果表明:负载树脂对As(V)的去除效果比原树脂有很大提高;吸附As(V)后的2种负载树脂,均能较好地解吸并可重新用于对As(V)的吸附实验。
Two kinds of MnO2-1oaded resins were prepared and analyzed by SEM and EDS, its As( V ) removal efficiency was investigated. The results showed that the adsorption of loaded resin to As ( V ) was more than that of before. Two loaded resins adsorbed As( V ) could be well desorpted and recycled for the sorption As (w).
