纤维素基磁性聚偕胺肟树脂研究：HAuCl4在树脂上的吸附与还原

Studies of Cellulose -Based Magnetic Polyamidoxime Adsorbents Adsorption and Reduetion of HAuCl 4 on BMAO

摘要: 研究了ＨＡｕＣｌ４在碱式纤维素基磁性聚偕胺肟树脂上的吸附动力学。吸附容量与吸附时间关系在初吸附的３０ｍｉｎ内可表示为Ｑ＝０．６４ｔ＾０．４。粒内扩散是吸附速度的控制阶段。在吸附过程中，同时发生氧化还原反应，Ａｕ（０）以不同聚集态附着在树脂表面。

Abstract: The adsorption kinetics of alkaline cellulose-based magnetie polyamidoxime adsorbent (BMAO) for HAuCl 4 was investigated. The relation between the adsorption capacity and the contact time within the initial 30 minutes may be expressed as Q=0.64t 0.4
