Utilizing oil palm sterilization condensate as methylene blue adsorbent.
This study explores the transformation of oil condensate waste (OCW) into activated carbons (ACs) as an efficient solution for managing condensate waste within palm oil mill, while providing a sustainable alternative for dye removal from wastewater. OCW was chemically activated using sulfuric acid (CH samples) and zinc chloride (CZ samples), followed by comprehensive characterization of their elemental composition, surface chemistry, and textural properties. The resulting activated carbons exhibited specific surface areas ranging from 427.85 to 493.42 m2/g with the maximum adsorption capacities of 230.5 mg/g. Adsorption performance was evaluated using isotherm and kinetic models, with the pseudo-second-order model providing the best fit, indicative of a chemisorption mechanism. Thermodynamic parameters further revealed that the adsorption process was both endothermic and spontaneous in nature. The results demonstrate the potential of activated carbons derived from OCW as efficient and sustainable adsorbents for wastewater treatment applications.
期刊介绍：
The International Journal of Phytoremediation (IJP) is the first journal devoted to the publication of laboratory and field research describing the use of plant systems to solve environmental problems by enabling the remediation of soil, water, and air quality and by restoring ecosystem services in managed landscapes. Traditional phytoremediation has largely focused on soil and groundwater clean-up of hazardous contaminants. Phytotechnology expands this umbrella to include many of the natural resource management challenges we face in cities, on farms, and other landscapes more integrated with daily public activities. Wetlands that treat wastewater, rain gardens that treat stormwater, poplar tree plantings that contain pollutants, urban tree canopies that treat air pollution, and specialized plants that treat decommissioned mine sites are just a few examples of phytotechnologies.
