SARS-CoV-2 is a novel coronavirus that was isolated and identified for the first time in Wuhan, China in 2019. Nowadays, it is a worldwide danger and the WHO named it a pandemic. In this investigation, a functionalization post-synthesis method was used to assess the ability of an adapted SBA-15 surface as a sorbent to load the drug from an aqueous medium. Different characterization approaches were used to determine the characterization of the substance before and after functionalization such as X-ray diffraction (XRD), Fourier transform infrared (FTIR) spectroscopy, scanning electron microscopy (SEM), nitrogen adsorption-desorption porosimetry (Brunauer-Emmett-Teller) BET surface area analysis, and thermal gravimetric analysis (TGA). Batch adsorption testing was carried out in a single adsorption device to find the impact of multiple variables on the drug amoxicillin charge output. The following parameters were studied: 0-72 hr. contact time, 20-120 mg/l initial concentration, and 20-250 mg of NH-SBA-15 dose. The outcomes from such experiments revealed the strong influence and behavior of the amino-functional group to increase the drug's load. Drug delivery outcomes studies found that amoxicillin loading was directly related to NH-SBA-15 contact time and dose, but indirectly related to primary concentration. It was observed that 80% of amoxicillin was loaded while the best release test results were 1 hour and 51%.
SARS-CoV-2 是一种新型冠状病毒,于 2019 年在中国武汉首次被分离和鉴定。如今,它是一个全球性的威胁,世界卫生组织将其命名为大流行。在这项研究中,采用了一种功能化后合成方法来评估经改良的 SBA-15 表面作为吸附剂从水介质中加载药物的能力。采用了不同的表征方法来确定功能化前后物质的特征,例如 X 射线衍射(XRD)、傅里叶变换红外(FTIR)光谱、扫描电子显微镜(SEM)、氮吸附-解吸孔隙率(Brunauer-Emmett-Teller)BET 表面积分析和热重分析(TGA)。在单个吸附装置中进行了批量吸附测试,以研究多个变量对阿莫西林药物负载输出的影响。研究了以下参数:0-72 小时接触时间、20-120 毫克/升初始浓度和 20-250 毫克 NH-SBA-15 剂量。这些实验的结果表明,氨基官能团对增加药物负载具有很强的影响和作用。药物输送结果研究发现,阿莫西林的负载与 NH-SBA-15 的接触时间和剂量直接相关,但与初始浓度间接相关。观察到 80%的阿莫西林被负载,而最佳释放测试结果为 1 小时和 51%。
