Abstract
Coagulation behaviour of binary H-clay mixtures of kaolinite and montmorillonite
in dilute suspension has been studied in the presence of various cations. It has
been observed that the coagulation and charge reversal characteristics of one clay
constituent is modified by the other in presence of electrolytes. The extent of modification
depends upon the nature and proportion of each electrolyte and on the
composition of the mixture. The coagulating power as well as charge reversal capacity
of cations increases in the following way: ThH > H+ > Ca+2 > Na+. An attempt
has been made to explain these characteristics.-
