To evaluate the relative flocculating power of allophane and imogolite, we conducted a series of flocculation experiment using allophane and imogolite sols and their mixtures. Imogolite was more effective than allophane for all five clay suspensions used. The residual turbidities of test montmorillonite suspensions after treatment with mixed allophane and imogolite sols were nearly equal to those calculated under the assumption that the contribution of allophane and imogolite was additive. But the experimental turbidity was much higher than the calculated one for a soil clay suspension.
