Two forms of activated carbon (i.e., granular and powdered forms) used to test mercury removal in solution. These activated carbons were obtained from the shells of a palmae biomass and used in mercury ion removal in aquatic systems. The African palmae shell taken out from a broadly and simply full-fledged palm tree. This biomass serves as a precursor in the formulation of activated carbons not documented. The powdered and granular fractions of activated carbons described for chemical composition, isoelectric point, and surface area. The mechanism of reactions and the kinetics involved were studied using the results of protonation and rate limitations. The parameters used in the batch mode study included pH, contact time, initial concentration of the adsorbate and the dose of the activated carbons. A comparison of performances, contact time demonstrated the highest adsorption efficiency of 93% for the powdered activated carbon and 92% for the granular activated carbon. The dosage recorded the lowest adsorption efficiency of 84% using granular activated carbon. Comparatively, this study brought to the fore that activated carbon derived from the Plamae biomass remains a novel bio-sorbent

从棕榈科生物质中制备粉末状和颗粒状活性炭以去除汞

两种形式的活性炭(即颗粒状和粉末状)用于测试溶液中的汞去除。这些活性炭从棕榈生物质的壳中获得,并用于水生系统中的汞离子去除。从一棵宽阔而成熟的棕榈树中取出的非洲棕榈科贝壳。该生物质充当未记录的活性炭配方的前体。描述了活性炭的粉末状和颗粒状部分的化学组成,等电点和表面积。使用质子化和速率限制的结果研究了反应的机理和动力学。批处理模式研究中使用的参数包括pH值,接触时间,吸附物的初始浓度和活性炭的剂量。表演比较 接触时间表明,粉末状活性炭的最高吸附效率为93%,颗粒状活性炭为92%。该剂量使用颗粒状活性炭记录的最低吸附效率为84%。相比之下,这项研究突显了源自Plamae生物质的活性炭仍然是一种新型生物吸附剂
