In this review paper, the ill effects of pharmaceuticals (PhAs) on the environment and their adsorption on graphene oxide (GO) and graphene oxide-based (GO-based) nanomaterials have been summarised and discussed. The adsorption of prominent PhAs discussed herein includes beta-blockers (atenolol and propranolol), antibiotics (tetracycline, ciprofloxacin and sulfamethoxazole), pharmaceutically active compounds (carbamazepine) and analgesics such as diclofenac. The adsorption of PhAs strictly depends upon the experimental conditions such as pH, adsorbent and adsorbate concentrations, temperature, ionic strength, etc. To understand the adsorption mechanism and feasibility of the adsorption process, the adsorption isotherms, thermodynamics and kinetic studies were also considered. Except for some cases, GO and its derivatives show excellent adsorption capacities for PhAs, which is crucial for their applications in the environmental pollution cleanup.
在这篇综述论文中，总结并讨论了药物（PhAs）对环境的不良影响及其在氧化石墨烯（GO）和基于氧化石墨烯（GO基）的纳米材料上的吸附情况。本文讨论的主要PhAs的吸附包括β-受体阻滞剂（阿替洛尔和普萘洛尔）、抗生素（四环素、环丙沙星和磺胺甲恶唑）、药物活性化合物（卡马西平）以及诸如双氯芬酸之类的镇痛药。PhAs的吸附严格取决于实验条件，如pH值、吸附剂和吸附质浓度、温度、离子强度等。为了理解吸附过程的吸附机理和可行性，还考虑了吸附等温线、热力学和动力学研究。除了某些情况外，GO及其衍生物对PhAs表现出优异的吸附能力，这对它们在环境污染清理中的应用至关重要。
