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。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. The adsorption capacity reduced rapidly if an acid or an alkaline liquor is added to the H 2PtCl 6 solution.
