摘要

本研究采用PVA/琼脂/麦芽糊精合成气凝胶去除水中的抗生素环丙沙星(CFX)。采用响应面法(RSM)研究影响吸附过程的因素之间的关系，从而优化吸附效率，更好地改进吸附过程。研究结果如下:pH2, CFX初始浓度51 mg L−1，吸附剂用量0.16 g L−1，吸附时间120 min，温度51.5℃达到最大吸附量。最大添加量为38.63 mg g−1。实验数据符合拟二次动力学模型和Langmuir、Temkin等温线模型。本研究的复合气凝胶吸附剂(AE)是去除水中抗生素污染的潜在吸附剂。

Optimization of the removal of the antibiotic ciprofloxacin by composite aerogels based on PVA/agar/maltodextrin

In this study, we used a synthetic aerogel based on PVA/agar/maltodextrin to remove the antibiotic ciprofloxacin (CFX) from aqueous media. Response surface method (RSM) is used to study the relationship between the factors affecting the adsorption process, thereby optimizing the adsorption efficiency, and making decisions on improving the adsorption process better sub. The research results obtained are as follows: pH2, initial CFX concentration 51 mg L −1 , adsorbent dosage 0.16 g L −1 , adsorption time 120 min, and temperature 51.5 °C reached the maximum adsorption capacity. The maximum additive is 38.63 mg g −1 . The experimental data agree with the pseudo-quadratic kinetic model and the Langmuir and Temkin isotherm models. The composite aerogel adsorbent (AE) in this study is a potential candidate for adsorbent to remove antibiotic contamination in aqueous media.

期刊介绍： The Journal of Chemical Research is a monthly journal which has a broad international authorship and publishes research papers and reviews in all branches of experimental chemistry. Established in 1977 as a joint venture by the British, French and German chemical societies it maintains the high standards set by the founding societies. Each paper is independently peer reviewed and only carefully evaluated contributions are accepted. Recent papers have described new synthetic methods, new heterocyclic compounds, new natural products, and the inorganic chemistry of metal complexes.
