Activated carbons (ACs) can be used not only for liquid but also for vapour phase applications, such as water treatment, deodorisation, gas purification and air treatment. In the present study, activated carbons produced from agricultural residues (olive kernel, corn cobs, rapeseed stalks and soya stalks) via physical steam activation were tested for the removal of Bromopropylate (BP) from water. For the characterization of the activated carbons ICP, SEM, FTIR and XRD analyses were performed. Adsorption kinetics and equilibrium isotherms were investigated for all biomass activated carbons in aqueous solutions. Experimental data of BP adsorption have fitted best to the pseudo 2nd-order kinetic model and Langmuir isotherm. The study resulted that corn cobs showed better adsorption capacity than the other biomass ACs. Comparison among ACs from biomass and commercial ones (F400 and Norit GL50) revealed that the first can be equally effective for the removal of BP from water with the latter.
活性炭不仅可用于液相应用，还可用于气相应用，例如水处理、除臭、气体净化和空气处理。在本研究中，通过物理蒸汽活化法，以农业废弃物（橄榄核、玉米棒子、油菜秸秆和大豆秸秆）为原料制备的活性炭，用于从水中去除溴丙酯（BP）。为了对活性炭进行表征，进行了 ICP、SEM、FTIR 和 XRD 分析。在水溶液中，对所有生物质活性炭的吸附动力学和平衡等温线进行了研究。BP 吸附的实验数据最符合准 2 级动力学模型和 Langmuir 等温线。研究表明，玉米棒子的吸附能力优于其他生物质活性炭。对生物质活性炭和商业活性炭（F400 和 Norit GL50）的比较表明，前者在去除水中 BP 方面与后者同样有效。
