Comparison of methylene blue adsorption on

01/01/2018· The amount of montmorillonite in bentonite, which is positively correlated with the degree of the useful characteristics of bentonite, can be determined using the methylene blue () test. The test measures the maximum amount of cation that can be adsorbed onto the surface of montmorillonite in the bentonite. When cations are adsorbed onto the montmorillonite surface, the cations replace cations at montmorillonite exchange sites. Therefore, the maximum

Bentonite surface modification and characterization

The bentonite used for this study was purchased from the Semnan-Iran bentonite mine and NH 3, in which the increased absorption capacity could be attributed to decreasing crystallinity of Al and Fe oxides in the FAB during aging and drying, causing higher sorption capacities due to higher reactivity of surface functional groups (Zhu et al. 2009a). This result is compatible with studies

Mineral Notes: Bentonite • Snowden

Bentonite is often weathered or oxidised close to outcrop – such processes cause changes in properties, e.g. oxidised bentonite may swell more and have higher viscosity than oxidised bentonite. This variation was described by Williams et al. (1954) "as a function of the overburden" – when they noted that blue (fresh) clay at depth changed to yellow (oxidised) clay near surface and that
