Abstract

Recent study has indicated the potential use of pectin as a sacrificial agent. In this paper, we
investigated the ability of pectin in reducing surfactant adsorption onto silica surface. The
impact of salinity on the adsorption of surfactants will therefore be the key subject of this article.
After the adsorption process, we measured the surfactant concentration using titration method.
The surfactant solution was titrated with Hyamine solution using Metrohm Titrando 888. The
effect of four different salt concentrations have been investigated which are 0, 10 000, 30 000
and 50 000 ppm. The outcome of static adsorption test shows that surfactant adsorption
increases with the increasing of salt concentrations. Results from static adsorption test shows
that the adsorption values for 0, 10 000, 30 000 and 50 000 ppm of salinity are 1.22, 2.52, 3.74
and 6.37 mg/g, respectively. However, when silica sand was treated with pectin solution,
surfactant adsorption on silica sand shows up to 50% reduction. Thus, from this result, pectin
showed a great potential in reducing surfactant adsorption.
