Abstract

The intensive use of fossil fuels has led to a significant increase in air pollution, which negatively affects human health and the environment. Fly ash (FA), a byproduct of coal combustion, has great potential as an adsorbent for hazardous gas pollutants due to its physical and chemical properties. This research aims to evaluate the effectiveness of fly ash as an adsorbent in reducing gas pollutants such as CO2, SO2, and NO2, as well as to examine the influence of temperature and material characteristics on adsorption capacity. The results indicate that the maximum adsorption capacity for each gas pollutant is achieved at different temperatures, fly ash demonstrating the highest performance at 150 °C for CO2 adsorption, achieving an efficiency of 94.7%. For SO2 and NO2, the optimum temperatures are 200 °C, with efficiencies of 72.17% and 100%, respectively. This study also emphasizes the importance of selecting the appropriate characteristics of the adsorbent material to enhance adsorption efficiency. This finding has the potential to support the development of more efficient and sustainable air pollution reduction technologies in the future, by utilizing industrial waste such as fly ash as an innovative solution.

Abstract

Palm oil mill effluent (POME) is a liquid waste from the palm oil industry. This waste contains high levels of organic pollutants and can contribute to environmental pollution. Current technologies effectively degrade these pollutants but are often not environmentally friendly and expensive. Phytoremediation combined with an adsorption system using ammonium polymers is expected to address these challenges. Vetiver grass (Chrysopogon zizanioides) and ammonium polymers have been separately tested and proven capable of degrading pollutants in wastewater. The study began by modifying the planting medium for vetiver grass with gravel:polymer:soil ratio of 3:5:2. The modified net pot was then placed in a floating treatment wetland reactor for POME treatment over a remediation period of 7 days. For comparison, a control experiment was conducted using plants without polymers in the planting medium. The results showed a COD degradation of approximately 75% in POME after treatment. The reduction in COD continued to improve with increasing remediation time, reaching its peak on the seventh day. The modified planting medium also influenced plant growth, as the polymer adsorbed some phosphate and nitrate.

Abstract

Rice husk is a natural source of silica that has the potential to be utilized in various applications, especially in industrial wastewater treatment. This study aims to determine the effect of NaOH concentration on the surface area and pore volume of silica gel from rice husk as an adsorbent. The method used is sol-gel with variations in NaOH concentration, namely 1, 2, and 3 M. The process of making silica gel consists of four steps. The silica gel manufacturing process consists of four steps: (1) combustion of rice husk using a furnace, (2) preparation of sodium silicate solution, (3) formation of silica gel through the addition of HCl, and (4) sample testing. Based on XRF analysis, rice husk ash is rich in silica (SiO₂) with a concentration of up to 32.189%, while water content testing shows that the 2 M NaOH concentration provides the largest decrease in water content (96%), higher than the concentrations of 1 M and 3 M, which reach 95%, in line with the results of BET analysis showing optimum conditions at a concentration of 2 M producing the highest surface area (138.720 m²/g) and the largest pore volume (0.673 cm³/g). The 1 M NaOH concentration produced a smaller surface area of 73.869 m²/g with a pore volume of 0.501 cm³/g. Meanwhile, the 3 M NaOH concentration decreased the surface area to 111.626 m²/g with a pore volume of (0.640 cm³/g). Overall, the 2 M NaOH concentration proved to be the most effective in increasing surface area and pore volume. Thus, the resulting silica gel is very suitable for adsorption applications, especially in the treatment of industrial wastewater.
