摘要: 研究了纤维素基磁性聚偕胺肟树脂吸附氯铂酸的过程。接触25min时,吸附容量达217mgPt/g·R。吸附速度受控于粒内扩散和化学反应。在H2PtCl6溶液中添加酸或碱均使吸附容量急剧下降。Abstract: The alkaline cellulose-based magnetic polyamidoxime resin was used as an adsorbent for chloroplatinic acid. The adsorption capacity was measured to be 217mg/gR after 25 min. The adsorption rate is controlled by the inta-particle transport of the ions. Th
