Abstract
Low-cost adsorbent was prepared from volcanicash of Mount Kelud in Indonesia which erupted in 2014 andremained million cubic of ash. The purpose of this study was toinvestigate the adsorption capacity of volcano ash to removeCu(II) in water. Some parameters such as mass of the adsorbent,pH of solution, and shaking time were investigated in order toknow the adsorption ability of the adsorbent. FTIR and SEMwere utilized in order to know the functional group and surfaceof adsorbent. The presence of carboxyl and hydroxyl functionalgroups in this adsorbent were important in the process ofadsorption. It was found that pH 6 of solution and 120 minutesof shaking time was a suitable condition for this adsorbent inadsorbing copper ion. Langmuir isotherm adsorption model wasfit for this adsorbent and the adsorption capacity for Cu (II) was82.64 mg/g.
