摘要
本文运用表面络合的原理和扩散层模式 ,研究了内蒙古清水河县喇嘛湾黄河干流沉积物的表面特征。根据酸碱滴定实验测得的沉积物样品的零电点 PH( PZC) ,表面质子电荷密度 σH 及总吸附位 NS,应用扩散层模式 ,用 FITEQL程序计算法求定了样品的表面固有常数。研究表明 ,应用扩散层模式研究天然水体沉积物的表面特征是可行的 ,在一定程度上能较好地吻合实验数据。
The surface characterisitics of the LaMa Wan sediment in the middle stream of the Yellow River in Inner Mongolia region is studied according to the surface complexation approach. aceording to the point of zero charge PH PZC ,the surface charge σ H and the total adsorptive sites of the sample reaching through potentiomeric titration experiments, The surface intrinsic constance were obtained with diffuse layer model by the FITEOL optimization method. It shows that the diffuse layer model can successfully fit the experimental data to some extent.
