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

为了快速有效地去除各种药物，开发了新的水处理技术，并通过使用合成水样和实际水样进行了评估。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现场降解它们。表面活性剂辅助沉淀是通过在阴离子表面活性剂存在下生成氢氧化铝实现的。这种方法几乎完全去除了各种各样的药物。以上两种方法都成功地利用了表面活性物质分子的疏水区进行有效分离。聚电解质-表面活性剂混凝在过氧化物酶和过氧化氢的辅助下可有效去除雌激素。壳聚糖和聚烯丙胺偶联的热响应性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的情况下，不同的有毒微量元素被同时去除。此外，在Sephadex凝胶上的吸附和连续解吸被用来研究临床上使用的Gd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 .
