ABSTRACT

Indonesia’s textile industry has been increased dramatically in the last several years. As a tropical country, Indonesia provides an adsorbent material abundant in nature which can adsorb dyestuff. One of alternatif adsorbent material available abundantly in Indonesia is volcanic ash soil. However, the capabilities of volcanic ash soil removing dyestuff in water were low. Therefore, the development of material is necessary to enhance the adsorption capacity. In this research, enhancing the adsorption ability of volcanic ash soil was done by adding alkaline solution with concentration of 0.5, 1.5 and 3.0 mol/L resulting A1, A2 and A3, respectively. The ability of developed materials from soil to adsorb methylene blue (MB) dye was tested in different adsorbent dose and contact time. The result showed that developed material had a higher adsorption capacity of methylene blue than volcanic ash soil. The optimum adsorption condition was obtained at 0.15 g of adsorbent dose for 24 hours of contact time where volcanic ash soil, A1, A2 and A3 were able to adsorb methylene blue dye (100 mg/L) with adsorption capacity of 5.72, 6.99, 6.90 and 6.16 mg/g, respectively. In addition, developing materials from soil also had better regeneration ability than soil through the fenton process.
