摘要
以竞争吸附的一般模式为基础,修正了竞争吸附方程。研究了不同实验条件下修正竞争吸附方程的变化形式,为改进实验设计提供了理论依据。修正竞争吸附方程应用于描述pH对土壤吸附钴的影响,取得了满意的结果。
Competitive adsorption equation was modified based on the fact that the competitive adsorption reaction often observed can be described as:
S(M1)m + M2 = SM2 + mM1. The modified competitive adsorption equation is as follows:
x2 =k2Mc2/(1+k2c2+ k1c1~m)
The newly introduced parameter m is not only an indicator of adsorption mechanism but also a measure of surface character of the adsorbent. The result was satisfactory when applying this equation to describe the effect of pH on cobalt adsorption on soils. The relative error of calculated and measured data was below 10%.
