2012-7-1 · The dry grinding treatment can disaggregate the crystal bundles of palygorskite and is favorable to generate mesopores and micropores. The adsorption efficiencies of grinded palygorskite for methylene blue were enhanced owing to the availability of more shielded adsorption sites and increasing specific surface area, micropore volume and mesopore volume.
