絮凝沉降的温度效应

The Effect of Temperature on Flocculation Settling

用传统的化学动力学方法讨论了温度对絮凝过程的影响,测定了木质素溶液在不同温度时被聚氯化铝铁(PAFC)絮凝的絮凝沉降曲线,讨论了曲线上拐点的意义,并估算出该胶体溶液絮凝时的活化能,它相当于DLVO理论为胶体粒子间的势能能垒φm,实验得出φm≈16.

The effect of temperature on flocculation settling process was discussed in the view of the traditional chemical kinetics. Moreover, the flocculation settlement curves of the lignin locution were determined at deferent temperatures under the condition of the polyaluminum ferric chloride flocculation, the sense of the inflexion point of the curve was discussed, and the acaivation energy of the colloid solution flocculatiov was ehimated, which corresponds to the potential-energy（Фm） between sol particles according to DLVO theory. The（vm） was given about 16.5KT through experiment.
