Abstract
In this paper, characterization, acid and base treatments, and adsorption assessment of the ash have been carried out to verify the ability of Merapi volcanic ash as an adsorbent. The characterizations were performed to determine the chemical composition by using ICP and surface area and pore volume by using surface area analyzer. The adsorbent ability was tested for removal of dyes, represented by naphtolis standard, and Batik waste water. The adsorption was carried by batch technique, in which adsorbent dose and adsorption time were varied to obtain the optimum condition. From the characterization, it is obtained that Merapi volcanic ash contains Si and Al as mayor elements, Fe, Ca, Mg, Na, and K with low percentage, and As, Mo, Cd, Cr, Cu, Mn and Pb with trace level. The adsorption study indicates that the Merapi volcanic ash can adsorbs the batik waste water and the adsorption increase by the increase in the weight of 49.6 % and stirrer time 50 minute can adsorb dyes waste of 3.9 gr/ml. Volcano ash is less suitable if it is used as adsorbent compared to natural zeolite
