Abstract

Optimization of pH and contact time on the adsorption of methylene blue by magnetite coated with humic acid (Fe3O4-HA) using the batch method was studied. The synthesis of magnetite coated humic acid (Fe3O4-HA) was carried out by coprecipitation method with a ratio of 1:2 (w/w). Optimization of pH and contact time of magnetite coated humic acid (Fe3O4-HA) was carried out with 30 ppm methylene blue concentration and 0.1 g Fe3O4-HA mass. The optimum pH and optimum contact time of magnetite coated humic acid (Fe3O4-HA) were at pH 7 with adsorption percent of 99,93% and 120 minutes with adsorption percent of 93,88%.
