Effect of alkali-treatment on the characteristics of natural zeolites with different compositions
(ACADEMIC PRESS INC ELSEVIER SCIENCE, 2018)
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, ...
Role of Modification of Natural Zeolite in Removal of Arsenic from Aqueous Solutions
(SLOVENSKO KEMIJSKO DRUSTVO, 2018)
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 ...
