Structures of nonionic surfactant modified montmorillonites and their enhanced adsorption capacities towards a cationic organic dye

Nonionic surfactant modified montmorillonites were prepared and applied for the adsorption of cationic organic dye MB. The adsorption mechanism of MB on the prepared organoclay was proposed to be the synergistic effect of ion exchange, partition adsorption, hydrogen bonding and electrostatic interactions.180
