humic acid silica sand behaviour of a humic acid in the presence of silica and 2) dissolution rate of silica in the presence of the humic acid. The products were analyzed mainly by visible and infrared spectroscopy and liquid chromatography. Materials Silica gel (Cica) for flush chromatography was used for the inorganic material.
Very low adsorption of humic acid on colloidal silica was also observed using Quartz crystal microbalance with dissipation (QCM-D) and zeta potential measurements.
