Abstract:
Bagasse ash contains relatively high silica and can be used as a source of silica in zeolite synthesis. The presence of cationic surfactant CTA+ can increase the crystallinity of zeolite. This research examines the effect of CTA+ surfactant concentration on zeolite crystallinity. The synthesis method is hydrothermal with a temperature of 150?C for seven days. The calcination temperature to decompose CTA+ surfactant is 650?C. The results showed samples without CTA+ were a mixture of Hydrogen Aluminum Silicate (HAS), Aluminum Silicate Hydroxide, and Kaolit. In contrast, samples with CTA+ surfactants produced a variety of Aluminum Silicate Hydroxide,kaolite, and Donbassite. From this study, it can be concluded that the greater the concentration of surfactants, the greater the crystallinity of the product and the emergence of new minerals, namely donbassite.
