UTILIZATION OF ZEOLITE 4A SYNTHESIZED FROM SILICA IN RICE HUSK ASH FOR AMMONIA REMOVAL
Main Article Content
Abstract
In this project, rice husk – a form of agricultural waste, was used as a potential raw material to extract silica, which produced zeolite to adsorb ammonia in the exhaust gas as well as environmental remediation. The obtained rice husk ash sample has high purity with 97,10% SiO2 by weight. XRD and SEM results demonstrate that zeolite 4A sample crystallizes in the form of characteristic cubes. BET result suggests that the specific surface area of material is 2,549 m2/g. Moreover, this paper also evaluated the ammonia treatment performance of the synthetic zeolite 4A sample by establishing the testing model. Under the conditions of the optimal parameters, the study observed zeolite 4A sample with ammonia treatment performance up to 70,16%, as well as the cumulative adsorption capacity and time to reach the breakthrough and saturation point: 5,75 mg/g and 180 minutes; 7,26 mg/g and 330 minutes.
