Abstract：
The contamination of water by pharmaceutical pollutants is a major issue these days due to excessive use of these ingredients in modern life. This study evaluated the adsorption and effectiveness of a low-cost composite prepared from heavy sugarcane ash (HSA) fused with polyethylene terephthalate (PET) and functionalized with iron (Fe3+) in a dynamic system through a fixed-bed column. The solution of synthetic drugs was prepared and placed in a reservoir, using a peristaltic pump the solution is run onto the fixed bed column at a flow rate of 2 mL min-1. Saturation time and adsorption capacity were evaluated by centrifugation and extraction after a regular interval of 2 h from the adsorption column. The samples were analyzed using high-performance liquid chromatography (HPLC) and the data was modeled for quantification. For DIC removal, an adsorption capacity of 324.34 μg. g-1 and a saturation time of 22 h were observed, while the adsorption capacity of NAP was 956.49 μg. g-1, with a saturation time of 8 h. Thus, the PETSCA/Fe3+ adsorbent proved to be quite efficient for removing the pharmaceutical pollutants, with a longer period of operation for DIC removal. These findings suggested that a highly efficient bed column made from a less expensive waste material and could be used to remove hazardous pharmaceutical contaminants.
摘要：
由于在现代生活中过度使用这些成分,药物污染物对水的污染是当今的主要问题。这项研究评估了低成本复合材料的吸附和有效性，该复合材料由重甘蔗灰（HSA）与聚对苯二甲酸乙二醇酯（PET）融合并通过固定床柱在动态系统中与铁（Fe3）官能化。制备合成药物的溶液并将其放入储库中，使用蠕动泵将溶液以2mLmin-1的流速流到固定床柱上。饱和时间和吸附能力通过离心和从吸附柱定期间隔2小时后提取来评估。使用高效液相色谱（HPLC）分析样品，并对数据进行建模以进行定量。对于DIC拆卸,吸附容量为324.34μg。观察到g-1和22h的饱和时间，NAP的吸附量为956.49μg。g-1，饱和时间为8小时。因此，PETSCA/Fe3+吸附剂被证明是非常有效的去除药物污染物，具有较长的DIC去除操作周期。这些发现表明，由较便宜的废物制成的高效床柱可用于去除有害的药物污染物。
