Removal of Cu (II) in Water by Using Adsorbent Based on Volcanic Ash of Mount Kelud in Indonesia
Eko Siswoyo, Annisa Firachmatika, and Ridho Babel Kautsar
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.
