Design of effective and environment-friendly treatment for the simultaneous removal of pharmaceuticals in medical waste water

开发了快速有效去除各种药物的新型水处理技术，并通过合成水样和实际水样进行了评价。使用阳离子表面活性剂和二氧化硅颗粒的胶束吸附可以有效地收集β -内酰胺类抗生素并在原位降解它们。表面活性剂辅助沉淀是在阴离子表面活性剂的存在下生成氢氧化铝实现的。这种方法几乎可以完全去除各种各样的药物。上述两种方法都成功地利用表面活性剂分子的疏水区进行了有效的分离。聚电解质-表面活性剂混凝法在过氧化物酶和过氧化氢的辅助下去除雌激素。壳聚糖和聚烯丙胺偶联热响应聚合物促进了酶促反应后酚类化合物的有效去除。在含有亚氨基二乙酸的螯合聚合物中，同时去除了不同的有毒微量元素。此外，在Sephadex凝胶上吸附，然后连续解吸，研究临床使用的钆配合物在环境水中的行为。

Novel water treatment techniques were developed for the rapid and effective removal of various pharmaceuticals and evaluated by using synthetic and actual water samples. Admicellar sorption using a cationic surfactant and silica particles allowed to collect beta-lactam antibiotics efficiently and degrade them in situ.Surfactant-assisted precipitation was achieved by generating aluminum hydroxide in thepresence of an anionic surfactant. The method offered the nearly complete removal of a wide variety of pharmaceuticals. The above two methods successfully used the hydrophobic region of surfactant molecules for the effective separation. Polyelectrolyte-surfactant coagulation was useful for the removal of estrogen with the aid of peroxidase and hydrogen peroxide. Chitosan- and polyallylamine-conjugated thermoresponsive polymers facilitated the effective removal of phenolic compounds after enzymatic reactions. In the case of chelating polymers containing iminodiacetic acid, different toxic trace elements were simultaneously removed. Further, sorption on Sephadex gel followed by successive desorption were developed to study the behavior of clinically used gadolinium complex in environmental water .
