Abstract

Hydrocarbon-impeded soil (HIS) is solid waste from spills or leaks during industrial activities that negatively impact the environment. This study aims to utilize HIS as catalyst support on MnO2 to degrade RhB (RhB) solution using Peroxymonosulfate (PMS) and to determine the optimum conditions for the catalyst to degrade RhB. The catalyst was synthesized by reacting HIS, calcined with KMnO4 with various catalyst supports with high and low Total contain Petroleum Hydrocarbon (TPH). The process degradation of Rhodamine Solution was carried out with various catalysts, PMS, and RhB concentrations. The catalyst was characterized using X-ray diffraction (XRD), Nitrogen gas adsorption-desorption (BET), and Scanning Electron Microscope-Energy Disperse Spectroscope (SEM-EDX). In this study,  the best catalyst performance was MnO2@H-TPH, which could activate PMS to degrade RhB with dye removal of 98% in about 180 min, at conditions 10 g/L RhB, 0.1 g/L catalyst, and 3 g/L PMS with the activation energy of 16.3 kJ/mol.

Abstract

Green chemistry has become trending recently, and the discovery of environmentally friendly catalysts is mandatory. Activated carbons (ACs) are one of the most environmentally friendly yet cheap materials that have the potential for catalyst application. Three commercially available ACs from Pancasari, Norit, and Chemical Supply were used as metal-free catalysts for advanced oxidation process (AOP) phenol removal in water in the presence of oxidants peroxydisulfate (PDS), and hydrogen peroxide (H2O2). It was found that ACs were effective to be used as catalysts for activating those oxidants to oxidize phenol in AOP reactions. In this study, the surface area of the catalyst significantly improved the phenol removal efficiency. ACs Pancasari (ACP) with the highest surface area has the best degradation performance of phenol removal with up to 99% removal efficiency in 60 minutes under the condition of [phenol] = 30 mg L-1, [ACP] = 0.2 g L-1, [PDS] = 3.3 mmol L-1, and T = 25oC. it was also found that the degradation process was significantly influenced by reaction temperature. Nevertheless, in this study, ACs display the potential as catalysts in the AOP process for wastewater treatments.

Abstract

Two MnOx, namely ?-MnO2@Mn2O3 and ?-MnO2 catalyst, were successfully synthesized using two different organic acids, tartaric and maleic acid, as a reduction in the redox process of KMnO4. The obtained catalysts are used in the AOP degradation reaction for paper mill effluent. The organic content in the effluent is analogous to the COD number in the effluent. The degradation process is depicted as a decrease in the COD number. The catalyst properties were characterized using X-ray diffraction (XRD), field emission scanning electron microscopy (FESEM), and N2 sorption. The obtained materials were then studied for PMS activation using Oxone® as a sulfate radical source for COD removal reactions. The ?-MnO2@Mn2O3, which is compromised by Mn (IV) and Mn (II, III), by using 0.3 gL-1 ?-MnO2@Mn2O3 has the best efficiency with almost 75% COD removal, higher than the ?-MnO2 catalyst. The activation energy of the ?-MnO2@Mn2O3 is measured up to 11.4 kJ mol-1.

Abstract

Various manganese oxides have been reported to be an active catalyst for degradation of a dye. The synthetic manganese oxides can be conducted by several methods with the products having the different physicochemical properties and structures. This research focused on the synthesis of  hausmanite-type manganese oxide (Mn2O3)  by hydrothermal method with different mole  ratio  of  KMnO4/glucose (3:1 and 2:3) and its application as a Fenton catalyst   for the degradation of methylene blue (MB). The as-synthesized manganese oxides were then characterized  by XRD for their structure and crystallinity and FTIR and Raman spectroscopy for the lattice vibrations. The average oxide state (AOS) of manganese in the as-synthesized manganese oxide was determined by the back titration method. The XRD results indicated  the presence of mixed phases with hausmanite  phase as major component and  cryptomelane and birnessite phases as minor ones. FTIR spectroscopy results showed the presence of O-Mn vibrations at wavelengths of 468 cm-1, 487cm-1, and 726 cm-1. In addition, Raman spectroscopy results clearly showed the  specific vibrations of hausmanite at 655 cm-1 and 653 cm-1, respectively. The low value of  Mn AOS was obtained when the oxide was prepared in low ratio KMnO4/glucose and short reaction time. The as-synthesized hausmanite was  tested  as the Fenton catalyt for the degradation of MB.  The as-synthesized hausmanite synthesized with different mole rasio and reaction time showed similar catalytic activity for the degradation of MB with the highest MB degradation of 90.76%
