제목 Study for Dispersion Stability of Ca(OH)2 Suspension by using Non-ionic Surfactant
초록 Ca(OH)2 suspension prepared by adding non-ionic surfactant, glycerin and polyethylene glycol (PEG) was evaluated as water treatment agents for removal of PO43- and F-. The amounts of surfactant were added from 0.05 wt% to 2 wt%. In case of glycerin, dispersion stability of Ca(OH)2 Suspension got higher above 0.5 wt% but Ca(OH)2 Suspension adding PEG was not shown a much difference depending on the surfactant. Removal ability of PO43- and F- was influenced not by adding amounts of surfactants but by adding amounts of Ca(OH)2 suspension. The Ca(OH)2 suspension was characterized by nitrogen adsorption-desorption, X-ray diffraction (XRD), scanning electronic microscopy (SEM), zeta-potential, particle size analyzer and viscosity to explain their excellent dispersion stability.
