Continuous discharge of ibuprofen, a pharmaceutical compound in local water systems is becoming a budding concern as seen from data procured from the past few decades. Increased concentrations of the compound in water reservoirs resulted in adverse effects on the environment. In order to prevent the deleterious impacts of increasing ibuprofen concentration in water bodies, application of cost effective and energy efficient elimination of ibuprofen (IBP) is needed. As a result, various techniques over time have been tested for IBP expulsion from aqueous media. However, adsorption and bioremediation are still the most realistic approaches to remove ibuprofen than conventional methods, like precipitation, reverse osmosis, ion exchange, nano-filtration etc., because of their lower initial cost, reduced electricity consumption, minimized sludge generation, local availability of precursor material etc. Various researchers have reported the applicability of the adsorption and bioremediation process in remediation of ibuprofen from water. Therefore, the present review article confers both the biosorption and bioremediation process towards IBP removal from water bodies and explicates the performances of various adsorbents and microorganisms derived from various sources. The presented review also substantially emphasizes on the effect of different parameters on sorptive uptake of ibuprofen, various isotherms and kinetic models, sorption mechanism and assessment of costs, which could enable future researchers to determine widespread use of reported adsorbents and microbes towards effective elimination of IBP from aqueous media.
从过去几十年获取的数据来看，局部水系中布洛芬这种药物化合物的持续排放正成为一个新兴的关注点。水库中该化合物浓度的增加对环境造成了不利影响。为了防止水中布洛芬浓度不断增加带来的有害影响，需要应用具有成本效益和节能效益的布洛芬（IBP）消除方法。因此，随着时间的推移，已经测试了各种技术来从水介质中排出 IBP。然而，与传统方法（如沉淀、反渗透、离子交换、纳滤等）相比，吸附和生物修复仍然是去除布洛芬的最现实方法，因为它们的初始成本更低、耗电量更低、产生的污泥更少、前体材料在当地更容易获得等。许多研究人员已经报告了吸附和生物修复过程在从水中去除布洛芬方面的适用性。因此，本综述文章既介绍了生物吸附和生物修复过程在从水体中去除 IBP 方面的应用，也阐述了各种吸附剂和微生物的性能，这些吸附剂和微生物来源于各种来源。本文还特别强调了不同参数对布洛芬吸附的影响、各种等温线和动力学模型、吸附机制以及成本评估，这将使未来的研究人员能够确定所报道的吸附剂和微生物在从水介质中有效去除 IBP 方面的广泛应用。
