This study aims to determine the metal oxide content of natural zeolite before being activated and after being activated. The activator used was hydrochloric acid6 M. Analysis of metal oxide content was carried out using the X-Ray Fluoresence (XRF) instrument. The results showed that there was a decrease in impurity levels after the zeolite was activated by acid. The content of Al2O3; SiO2; K2O and CaObefore activation were 2.15%; 86.34%; 4.32%; and 2.54% respectively, while after activation were 2.11%; 86.40%; 4.56%; and 2.78%respectively. The content of other metal oxides (impurity) generally decreases in levels after the zeolite is activated.
