Abstract

Hydoxysodalite was prepared by two different methods; using normal hydrothermal heating, and using a microwave assistant. Some heavy metals were selected and their removed capacity was chosen as a probe indicator for the properties of both methods. X-ray diffraction (XRD) was used for follow-up the crystallinity and the degree of crystal destruction upon copper ion exchange. The copper ion exchanged zeolite was used in hydroxylation of benzene as probe reaction.
The results showed that the microwave assisted prepared zeolite had lower crystallinity. Also, it showed a higher stability toward the ion exchange and higher catalytic activity per active centers.
