Surface modification of colloidal silica particles using cationic surfactant and the resulting adsorption of dyes

Surfactant interactions, self-association, and self-organizing properties can play an important role in customizing colloidal particles surface. Colloidal silica (CS) is an essential biocompatible material, which makes it a suitable candidate for various studies related to surface modifications. In this work, colloidal silica (SiO2) was synthesized using a modified Stober's process. Point of zero charge (PZC) was measured by standard pH...
