Abstract
Zeolite is a mineral which is presence quite abundant, especially in the Tegalrejo and surrounding areas, Gedangsari District, Gunungkidul Regency, Yogyakarta Special Region. This zeolite mineral is found in tuff claystone, tuffaceous sandstone and sandstone tuff. The cation exchange capability possessed by zeolites has long been of particular interest. This interest is proven through several previous studies to determine the cation exchange ability of zeolites. This research is important because it aims to identify the zeolite cation exchange capability of metal cations found in acid mine water samples. The cation exchange capability is carried out through a batch method which results are adjusted to the adsorption isotherm model. AAS analysis showed the sorbent sample had a K value of 0.243 with a maximum cation absorption value of 0.1681 mg / g of zeolite samples for Zn cation (zinc); K value 0.116 with a maximum cation absorption value of 0.8836 mg / g zeolite sample in the copper cation. Adsorption of Zn and Cu cations by zeolite samples is in accordance with the Langmuir isotherm adsorption model. Measurement of the pH value shows an initial pH value of 5.2 to 5.4 changed to 7.36-7.46 after the experiment. The results of the study concluded that zeolite can be used as an alternative to acid mine remediation, especially for Cu and Zn cation adsorption.
