Removal of Cu (II) in Water by Using Adsorbent Based on Volcanic Ash of Mount Kelud in Indonesia

Abstract—Low-cost adsorbent was prepared from volcanic ash of Mount Kelud in Indonesia which erupted in 2014 and remained million cubic of ash. The purpose of this study was to investigate the adsorption capacity of volcano ash to remove Cu(II) in water. Some parameters such as mass of the adsorbent, pH of solution, and shaking time were investigated in order to know the adsorption ability of the adsorbent. FTIR and SEM were utilized in order to know the functional group and surface of adsorbent. The presence of carboxyl and hydroxyl functional groups in this adsorbent were important in the process of adsorption. It was found that pH 6 of solution and 120 minutes of shaking time was a suitable condition for this adsorbent in adsorbing copper ion. Langmuir isotherm adsorption model was fit for this adsorbent and the adsorption capacity for Cu (II) was 82.64 mg/g.

Index Terms—Copper, low-cost adsorbent, mount Kelud, volcanic ash.
