five consecutive adsorption-desorption cycles. The maximal static saturated adsorption capacity of the resin is 206 mg/g at 333 K in the Pb2+ concentration range of 200-400 mg/L. The modified D401 chelating resin is an efficient adsorbent for the removal of Pb2+ from its single-metal ion solution.

of the ratio of desorption gas condensability were investigated based on a double bed five steps pressure swing adsorption (PSA). The results show that the temperature curves of different heights... column height. It enters a stability stage after 400 cycles. No SO2 is detected when the bed height is higher than 0.60 m. During the purge desorption and vacuum desorption stage, the ratio of desorption......
