摘要

受纳水体中存在药物或其活性代谢物,表明从废水中去除生物活性基质的效率不高。吸附似乎是去除这些物质最有效、最廉价的方法。以吸附剂为目标的废物管理是实现若干可持续发展目标的一种可行方法。本文研究了废水中两种最广泛使用的药物的去除情况。利用纺织废物衍生吸附剂从水和废水中去除双氯芬酸和卡马西平。通过测试几个工艺参数,如吸附时间、干扰无机离子的存在、溶解有机物的存在、溶液的初始 pH 值和离子强度以及各种水基质,验证了它们的去除效率。结果表明,双氯芬酸(57.1 毫克/克)和卡马西平(21.25 毫克/克)具有吸附能力。测试的工艺参数(pH 值、无机离子的存在、溶解的有机物、离子强度、水基质)证实,所提出的废料具有从水基质中去除药物的巨大潜力。

From Waste to Water Purification: Textile-Derived Sorbents for Pharmaceutical Removal
The presence of pharmaceuticals or their active metabolites in receiving waters is a sign of the inefficient removal of bioactive substrates from wastewater. Adsorption seems to be the most effective and inexpensive method of their removal. Waste management aimed at sorbents is a promising way to sustain several sustainable development goals. In the presented paper, the removal of the two most widely used drugs in the wastewater was examined. Diclofenac and carbamazepine were removed from water and wastewater using textile waste-derived sorbents. Their removal efficiency was verified by testing several process parameters such as the time of the sorption, the presence of interfering inorganic ions, the presence of dissolved organic matter, the initial pH and ionic strength of the solution, and various water matrices. The adsorption capacity was noted for diclofenac (57.1 mg/g) and carbamazepine (21.25 mg/g). The tested process parameters (pH, presence of inorganic ions, dissolved organic matter, ionic strength, water matrix) confirmed that the presented waste materials possessed a great potential for pharmaceutical removal from water matrices.
