Abstract

Functionalized banana stalk (BSAC) was investigated as a potential adsorbent in removing a commonly used pharmaceutical antimalaria drug, Lumefantrine (LUMF). The raw banana stalk was chemically treated with orthophosphoric acid to enhance its adsorptive properties. The effect of LUMF initial concentration, temperature, solution pH, and contact time on the adsorption process was studied using the batch equilibrium process. The surface characteristics of the prepared adsorbent were investigated using SEM, FTIR, proximate analysis, and the Boehm titration techniques. The FTIR spectra showed notable peaks that are responsible for the adsorptive uptake of LUMF. The micrograph from the SEM showed well-developed pores which can be attributed to the effect of the acid treatment, and results from the proximate analysis showed 73.92% carbon content which is a remarkable percentage for a favorable uptake. The sips isotherm model best fitted the experimental data with an R2 = 1, and a maximum adsorption capacity of 102.1 mg/g. The pseudo-second-order kinetic model best explains the kinetics of adsorption of LUMF onto BSAC with R2 values ranging from 0.9845-0.9997. Thermodynamic studies suggest that LUMF uptake by BSAC is endothermic, spontaneous, and thermodynamically favored. BSAC was found to be effective in removing LUMF from aqueous solutions.

功能化香蕉茎去除鲁美ntrine药物

研究了功能化香蕉茎（BSAC）作为一种潜在的吸附剂去除常用的抗疟药物鲁美芬特（LUMF）。用正磷酸对生香蕉茎进行化学处理，以提高其吸附性能。采用间歇平衡法研究了LUMF初始浓度、温度、溶液pH和接触时间对吸附过程的影响。利用扫描电镜、红外光谱、近红外光谱分析和Boehm滴定技术对制备的吸附剂的表面特性进行了研究。FTIR光谱显示出显著的峰，这些峰负责LUMF的吸附吸收。SEM的显微照片显示出发达的孔隙，这可归因于酸处理的效果，并且来自近似分析的结果显示73.92%的碳含量，这对于有利的吸收是显著的百分比。sips等温线模型最符合实验数据，R2=1，最大吸附量为102.1mg/g。伪二阶动力学模型最好地解释了LUMF在BSAC上的吸附动力学，R2值在0.9845-0.9997之间。热力学研究表明，BSAC吸收LUMF是吸热的、自发的和热力学上有利的。发现BSAC在从水溶液中去除LUMF方面是有效的。
