Abstract

The development in science and technology over the past few decades has changed the world a lot. In view of the changes caused in the environment, the results are disturbing. One such example is the bloom of the pharmaceutical industry which has lead to synthesis of many drugs which possess potency for curing a number of diseases. However, the accumulation of the unused drugs in semi-metabolized state in the natural water systems through manufacturing plants, hospitals or consumers at large, have led to a serious trouble. This review article aims to present a short summary of the various methods proposed for the removal of antibiotics and non-steroidal Anti-Inflammatory Drugs (NSAIDs) from aquatic systems through adsorbents synthesized using chitosan and its different structurally modified versions. Chitosan, being abundantly available in nature, has become the most preferable material as adsorbent for a variety of contaminants including dyes, heavy metals, fluoride, drugs, fertilizers, etc. Thus, we present three important structural modifications of chitosan namely crosslinked/grafted chitosan, chitosan hydrogels/microspheres and chitosan composites as potential adsorbents for commonly used antibiotics and drugs. The study also includes the optimized pH conditions for adsorption, isotherm, kinetics and mechanism of adsorption as well as maximum adsorption capacity obtained for the drug.

壳聚糖吸附剂吸附吸附水体中抗生素和非甾体抗炎药污染物的研究进展

在过去的几十年里，科学技术的发展已经改变了世界。考虑到环境的变化，结果令人不安。一个这样的例子是制药工业的繁荣，它导致了许多药物的合成，这些药物具有治疗许多疾病的效力。然而，未使用的半代谢状态的药物通过生产工厂、医院或广大消费者在自然水系中积累，导致了严重的麻烦。本文综述了利用壳聚糖及其不同结构改性的吸附剂从水生系统中去除抗生素和非甾体抗炎药的各种方法。壳聚糖在自然界中储量丰富，已成为染料、重金属、氟化物、药物、肥料等多种污染物最理想的吸附剂。因此，我们提出了三种重要的壳聚糖结构改性，即交联/接枝壳聚糖、壳聚糖水凝胶/微球和壳聚糖复合材料作为常用抗生素和药物的吸附剂。研究了该药物的最佳吸附pH条件、等温线、吸附动力学和机理以及获得的最大吸附量。图形抽象
