Abstract

The Sidoarjo Volcanic Mudflow has been one of Indonesia's ongoing national catastrophes since 2006. Numerous studies have been conducted to examine the potential applications of this abundant material due to its massive quantity. In this work, Sidoarjo Volcanic Mud was utilized as a dye-removing adsorbent in batik wastewater. To increase the effectiveness of Sidoarjo Volcanic Mud as an adsorbent, physical and chemical activation techniques were employed, and the results were compared to a control without activation. The sample was heated at 550 °C for three hours to be physically activated. The sample was chemically activated by applying 5N H2SO4 solution for 2.5 hours. In a batch system with an orbital shaker, adsorption tests were conducted for the color removal of pure and pre-treated batik wastewater. Using UV-Vis spectrophotometry, the decolorization of batik wastewater was monitored during the reaction. Due to the high concentration of apparent color in the sample, the effect of the adsorbent activation method was insignificant in pure batik wastewater. In contrast, the effect of the adsorbent activation method was evident in pre-treated batik wastewater, where up to 50% decolorization of the true color was achieved with chemically activated, 18.75% with no activation, and 23.30% with physical activation.

Abstract

Advanced Oxidation Processes (AOP), such as persulfate oxidation is a promising contaminant removal agent for treating wastewater. In this study, Sidoarjo volcanic mud (VM) was applied as heterogeneous catalyst to support the persulfate oxidation process for Congo Red (CR) dye removal. The Sidoarjo volcanic mud is known to have a high iron content, making it a potential catalyst in AOP. This study was conducted under conditions of pH 2, CR 50 mg/L, and catalyst dosage 0.5 g/L  and effective reaction volume of 300 mL. This experiment was conducted by comparing three types of catalysts: unmodified volcanic mud (UVM), impregnated volcanic mud (Fe-IVM), and calcined volcanic mud (CVM). The methods were carried out by comparing two methods, namely simultaneous and sequential. The obtained CR removal values for UVM, Fe-IVM, and CVM catalysts were 83.73%, 78.86%, 51.96% for simultaneous and 84.75%, 81.72%, and 87.69% for sequential method. Whereas the UVM catalyst has the highest CR removal value with a lower adsorption value of 16.89%. The production of sulfate radical analyzed by comparing the oxidation process of homogeneous and heterogeneous catalysts. It was shown that the application of VM catalyst as heterogeneous catalyst is very promising for dye removal in wastewater treatment.
