The presence of pharmaceutical pollutants, including antibiotic contaminants in the environment is one of the most important issues in the world today. We focused on elimination of amoxicillin (AMX) from aqueous media in micro Channel Y-Y shaped. The kinetic studies showed that the reaction kinetic was very fast and extraction equilibrium is attained within 20 s. Key operational parameters such as feed concentration, pH of aqueous solution, and extractant concentration and residence time were optimized. The maximum rate of AMX removal was determined 98.2%. Overall volumetric mass transfer coefficient of amoxicillin , is perused to specify the mass transfer performance. Much higher amoxicillin values acquired in the micro process compare with conventional extraction approved the amoxicillin is easily extracted with a higher ratio at micro-flow. The studies demonstrated that the micro solvent extraction process has considerable potential for environmentally friendly and would be a promising method for wastewater treatment of complex systems. On-chip liquid-phase microextraction coupled with UV-VIS was introduced.Extraction percentage of 98.2% was obtained using MDEHPA under best conditions.Microfluidic shows the considerable potential for environmentally friendly and amoxicillin removal from aqueous media.
药物污染物（包括环境中的抗生素污染物）的存在是当今世界最重要的问题之一。我们专注于在微 Y-Y 型通道中从水介质中去除阿莫西林（AMX）。动力学研究表明，反应动力学非常快，在 20 秒内达到萃取平衡。优化了关键操作参数，如进料浓度、水溶液 pH 值、萃取剂浓度和停留时间。阿莫西林去除的最高速率为 98.2%。阿莫西林的总体容积传质系数用于说明传质性能。在微通道中获得的阿莫西林值要高得多，这表明在微流条件下阿莫西林很容易以更高的比例被萃取。研究表明，微溶剂萃取工艺具有良好的环保潜力，有望成为处理复杂体系废水的有前途的方法。介绍了微流控芯片上液相微萃取与 UV-VIS 的结合。在最佳条件下，使用 MDEHPA 可获得 98.2%的萃取率。微流控技术显示出从水介质中去除阿莫西林的巨大潜力。
