摘    要:用天然麦饭石对海水及水溶液中重金属Cu(Ⅱ),Zn(Ⅱ)的吸附结果表明,麦饭石对海水及水溶液中的Cu(Ⅱ),Zn(Ⅱ)有较强的吸附作用,在温度一定时,吸附量随两种金属离子平衡浓度的变化规律,在水溶液中可用Langmuir等温方程或Freundich等温方程描述,海水及水溶液的PH值对吸附有较大影响。吸附率随PH的变化曲线呈“S”形。此外,测定了麦饭石对海水及水溶液中Cu(Ⅱ),Zn(Ⅱ)的饱和吸附

关 键 词:麦饭石  吸附量      海水

Abstract:The experiment results showed that Adsorptive capacity of metal ions by Mai Fan stone in aqueous solution,according to Freundlich equation and Langmuir equation,increased with the increase in metal ions equilibrium concentration when temperature and pH values are given,in sea water according to"three constants equation".
Keywords:Mai Fan stone  adsorptive capacity  ion-exchange
