Abstract

ABSTRACT Amines adsorbs at the solid-liquid interface when added to aqueous solution which contains quartz particles, under certain pH conditions, rendering these particles hydrophobic. [...]this hydrophobicity may be affected by the addition of starch into the system, which is capable of adsorbing mutually with amine due to the formation of a helical complex between the reagents, called clathrate. [...]the quartz particles reacquire a hydrophilic surface since the amine is hidden by the starch envelopment. In: Canadian Metallurgical Quarterly, v. 10, 229-235; Somasundaran, P.
