Natural zeolite (NZ) obtained from the Manisa-Demirci region of Turkey was modified by NaOH aqueous solutions (0.5-2.0 mol/dm(3)) and the adsorption capacity of natural and modified forms was determined for manganese ...

A series of natural zeolites with different compositions were modified by post-synthesis modification with sodium hydroxide (NaOH) solution. Natural and modified zeolites were characterized by XRD, SEM, nitrogen adsorption, ...

The adsorption of arsenic from aqueous solution onto natural and modified zeolites was investigated. The natural zeolites were modified by ion-exchange (NH4NO3) and addition of aluminum (Al-2(SO4)(3)). The natural and ...

The natural zeolite (NZ) was obtained from Sivas-Yavu of Turkey and modified by ion-exchange (NH4NO3), alkali treatment (NaOH) and addition of aluminum (Al-2(SO4)(3)). The natural and modified samples were characterized ...

Adsorption properties and column flotation were studied to investigate the interaction of the anionic and cationic collectors and flotation recoveries for talc mineral. Adsorption capacity is dependent on pH, adsorption ...
