Abstract

β-MnO2 was prepared and used to activate peroxymonosulphate for degradation of aqueous phenol. The sample was characterized by N2 adsorption, X-ray diffraction (XRD), scanning electron microscopy (SEM). The catalyst is highly effective in heterogeneous activation of PMS to produce sulfate radicals for phenol degradation compared with homogeneous oxidatiom. β-MnO2 could completely remove phenol in 30 min at the conditions of 25 ppm phenol, 0.4 g/L catalyst, 2 g/L PMS, and 25 oC. A pseudo first order model would fit to phenol degradation kinetics and activation energy was obtained as 38.2 kJ/mol.

Abstract

Wastewater of pulp and paper industry has low BOD5/COD ratio (average 0,3) while good biodegradability value was considered in the range over 0,5. These data indicate that lignin and its derivatives in the effluents exhibit slow degradation kinetics for conventional treatment process. There is an increasing interest in utilization of sulphate radical based advanced oxidation processes (SR-AOP) for destruction of slow degrading compounds. SR-AOP is based on the production of sulphate radicals as oxidizing agents. Sulphate radical can produce by activation of peroxymonosulfate. Metal free catalyst have been employed as the more effective activators for peroxymonosulfate to generate sulfate radical because the negative effect of leaching ions from heterogeneous metal catalyst can not fully neglected. Nitrogen doped three dimensional carbon framework (3D NCF) as metal free catalyst has been synthesized by annealing a zeolitic imidazolate framework (ZIF-67), followed by removing the cobalt metal. Physical properties were characterized by several techniques such as XRD. Effect the concentration of catalyst (0,1-0,4 g/L) was investigated in this research. Result indicating that 3D NCF exhibited remarkable degradation activity with the efficiency degradation of COD up to 88,22 % within 120 minutes at condition 0,4 g/L catalyst, 2,0 g/L PMS, 30oC and stirred constantly at 400 rpm. Keywords: advanced oxidation processes, metal free catalyst, nitrogen-doped three dimensional carbon, peroxymonosulfate, wastewater of pulp and paper

Abstract

Biodiesel is an alternative energy to replace fossil fuels. It can be synthesized by transesterification process of palm oils. Commonly the process of producing biodiesel was used NaOH or KOH as homogeneous catalyst which has the disadvantage because the formation of side products such as soaps and complexity of the separation of catalyst. This research aims to derive biodiesel from seed calophyllum inophyllum oil (CIO) through transesterification using heterogeneous base catalyst Na2SiO3/Fe3O4. Catalyst Na2SiO3/Fe3O4 was synthesized from fly ash palm oil, sodium hydroxide, and iron powder. Condition operation the transesterification are molar ratio of oil:methanol 1:9 and loading catalyst 3%-w with under stirring 300 rpm. The highest yield of biodiesel is 89,48% under the transesterification reaction temperature 60 oC, reaction time 2 hours. Density (40°C) of biodiesel is 862,56 kg/m3, kinematic viscosity (40°C) is 3,54 mm2/s, flash point is 140°C and acid value is 0,50 mg-KOH/g-biodiesel.Keyword: Biodiesel, Esterification, Catalyst, seed calophyllum inophyllum oil (CIO) and Transesterification.

Abstract

Rhodamine B is one of the various toxic dye that contributes significantly to environmental pollution, because it is non-biodegradable, toxic and harmful to the environment. One effort to reduce the amount of rhodamine b is the adsorption process. One of the good adsorbent that can be use for adsorbtion process is palm oil fly ash. The purpose of this study to aim the effect of adsorption temperature, pH, and adsorbent mass. Knowing the optimum conditions for reducing the levels of dye in the water, as well as determine the adsorption equilibrium models rhodamine b using fly ash oil modified with 0,1M HCl as an adsorbent. Fly ash modification processes are done by mixing fly ash and HCl in the ratio 1:10 of 0,M HCl solution. The adsorption process is conducted by mixing fly ash 0.5; 1; 1,5 and 2g/L and pH solution of rhodamine b 2; 4; 6; 8 with temperature of 30; 35; 45oC and with various of rhodamine b’s initial solution 10, 20, 30 dan 40ppm. The optimum conditions for reducing the levels of rhodamine B in water is the adsorbent mass of 2g/L, temperature of 45°C and pH 8 at 10ppm concentration rhodamnine’s solution.
