Abstract

The
aim of the present investigation was to analysis the interactions of colemanite
crystal surface with surrounding fluids and colloidal particles. Specifically,
in this research, the interactions between colemanite surface and glass
colloidal probe were studied using the atomic force microscopy (AFM). The
colloidal forces were measured in 0.001M NaCl aqueous solutions at pH values
from ~7 to 10 to explore a transition from attractive to repulsive forces when
the surface charge potential for colemanite changes from positive to negative
at isoelectric point (IEP) located near pH~10.

Keywords
