摘要
制备了载锰剑麻基活性炭纤维（ＳＡＣＦ－Ｍｎ），并研究了制备条件对ＳＡＣＦ－Ｍｎ的结构及表面形态的影响。研究表明：增大锰溶液的浓度，提高ｐＨ值，高价态的锰离子都有利于ＳＡＣＦ对锰的吸附；锰化合物的阴离子类型，不仅影响ＳＡＣＦ对锰的吸附。
Sisal based actived carbon fibers carrying manganese(SACF Mn)were prepared. Relationships among preparing conditions,crystalline structures and surface morphologies of SACF Mn were studied. Results show that adsorption amount and surface morphologies of SACF are related to Mn solution concentration,solution pH,Mn ion valence state,and type of anion species of Mn compound.Enhancing solution concentration and pH and higher Mn ion valence can increase the amount of manganese compound adsorbed on SACF The surface morphologies of SACF Mn with Cl ,SO 2 4 and NO 3 anions show netshaped,grain shaped and coral shaped patterns,respectively.
