Abstract

The acid-base properties of the glauconite surface has been studied by potentiometric titration. Using a surface complexation model with a constant exchange capacity, it was shown that positively charged surface centers and exchange centers dominate in the acidic pH region, and negatively charged centers dominate in the neutral and alkaline regions. The corresponding constants of acid-base equilibrium have been calculated. The data obtained were used to study the sorption of cadmium and lead on glauconite.

海绿石的表面性质研究
用电位滴定法研究了海绿石表面的酸碱性质。采用具有恒定交换容量的表面络合模型,发现在酸性pH区,表面中心和交换中心以带正电荷为主,而在中性和碱性区,表面中心以带负电荷为主。计算了相应的酸碱平衡常数。利用所得数据研究了海绿石对镉和铅的吸附。
