| Abstract | : | The aim of this study was to prepare and characterize a potential adsorbent based on zeolite from Klaten, Central Java, Indonesia. The pre-treatment of natural zeolite (ZA) consists of chemical activation using HCl (ZAA) and NaCl (ZAT). Cationic surfactant benzalkonium chloride was used for modification of the zeolitic surface. ZA, ZAA, ZAT, and modified zeolites were characterized by FTIR, XRD, and AAS. The cation exchange capacity (CEC) of the natural zeolite measured by 1 M NH4OAc method. Results show that the higher Si/Al ratio was achieved when natural zeolite was activated by the strong acid of HCl, but acid activation did not change the structure of the zeolite itself. The result of XRD analysis supports the AAS analysis result in which the degrees of crystallinity of zeolite increased after acid activation. The studies by FTIR and XRD analysis indicated that the zeolite structure remained unchanged after the modification with the cationic surfactant. Thus the activated and modified zeolites create a new material adsorbent to reduce pollutants in the environment. |
