| 摘 要： | 本文通过改变吸附的温度,测得不同离子的吸附量,根据分配系数D与温度T的关系式lnD=-ΔH°/RT+C作图,由其斜率求得反应的焓变,从而从理论上说明温度对吸附的影响,同时通过改变金属离子的浓度,根据Freundlich吸附等温式作出其吸附等温线,并求出有关常数,从而从理论上说明吸附反应进行的难易程度及树脂对金属离子吸附能力的大小。

| Abstract: | The various ion capacities of adsorption are measured by change of adsorption temperature,and the graphlines are made by the relation formula of coefficient of distribution D and temperature T:InD=-ΔH°/RT+C. With achievingenthalpy change of reaction, We illustrate the temperature influence on adsorption in theory,at the same time,the isothermallines of adsorption are done by change of meta1 ion density and Freundlich isothermal formula of adsorption,and the relatedconstants are achieved,thus,we can explain in theory the difficult or easy degree and the ability of adsorption for metalion. |
