- Description
- Adsorption equilibrium and kinetics of methylene blue (MB) onto silica gel and aluminum pillared montmorillonite was studied in a batch system. Variables of the system include contact time, salt concentration and initial methylene blue concentration. Langmuir and Freundlich isotherm models were applied to experimental equilibrium data of methylene blue adsorption. Both models were suitable for the parameters. The advantage of silica gel as applied to water treatment is its high porosity when compared to aluminum pillared montmorillonite clay. Water molecules adhere to the silica gels surface because it exhibits a lower vapour pressure than the surrounding air. When equilibrium of equal pressure is reached, no more adsorption occurs. Thus the higher the humidity of the surrounding air, the greater the amount of water that is adsorbed before equilibrium is reached. The increase in pressure loss on the silica gel filters is 1.5 - 2.0 times smaller than in the case of sand filters, Lorenc (2007).
