摘要/Abstract

摘要： 研究了氯化镁介质中分散剂聚丙烯酸在氧化铝表面的吸附情况．发现盐浓度和ＰＨ对吸附曲线均有显著影响．与氯化钠介质中的吸附情况相比，镁离子的存在使ＰＡＡ的吸附量明显提高，当ＰＡＡ加入浓度为１５７０ｍｇ／Ｌ时，对应吸附曲线的最大值．镁离子与聚丙烯酸形成络合聚合物吸附在氧化铝表面．

Abstract: The paper presents the results on the adsorption behaviour of polyacrylic acid onto alumina with the presence of magnesium ions. Both the salt concentration and pH have great influence on the adsorption isotherms. Comparing with the adsorption behaviour in sodium chlo- ride solution, magnesium ions can enhance the adsorption amount obviously. Magnesium ions are co-adsorbed onto alumina powders as a complex with PAA.

Key words: magnesium chloride solution, alumina, PAA, adsorption behaviour
