摘要

将ZnO纳米粒子（ZnO NPs）与羧甲基罗望子核胶原位混合，制备了新型生物复合材料。采用高分辨率透射电子显微镜（HR-TEM）、场发射扫描电子显微镜（FE-SEM）、傅立叶变换红外光谱（FTIR）、x射线衍射分析（XRD）和动态光散射（DLS）对CMTKG/ZnO纳米复合材料进行了表征。利用大量表征来证明ZnO NPs已经集成到生物聚合物基体中。使用高分辨率透射电子显微镜和x射线分析de Scherer方法，CMTKG/ZnO纳米复合材料的标准尺寸被开发为大于32–40 nm。使用纳米复合材料（CMTKG/ZnO）作为吸附剂从水溶液中去除铬（VI）。在接触时间为80分钟、铬（VI）浓度为30 mg/L、吸附剂部分为2.0 g/L、pH为7.0的条件下，纳米复合材料达到了最大吸附量。进一步研究了CMTKG/ZnO纳米复合材料对黄曲霉MTC-2799的抗真菌活性。

Carboxymethyl Tamarind Kernel Gum /ZnO- Biocomposite: As an Antifungal and Hazardous Metal Removal Agent

ZnO nanoparticles (ZnO NPs) were in situ mixed with carboxymethyl tamarind kernel gum to generate the new biocomposite. High-resolution transmission electron microscopy (HR-TEM), field emission scanning electron microscopy (FE-SEM), Fourier transform infrared (FTIR), x-ray diffraction analysis (XRD), and dynamic light scattering (DLS)were used to characterize the CMTKG/ZnO nanocomposites. Numerous characterizations were utilized to prove that ZnO NPs had been integrated into the biopolymer matrix. The standard size of the CMTKG/ZnO nanocomposites was developed to be greater than 32–40 nm using high-resolution transmission electron microscopy and x-ray analysis de-Scherer methods. Chromium (VI) was removed from the aqueous solution using the nanocomposite (CMTKG/ZnO) as an adsorbent. The nanocomposite reached its maximum adsorption during 80 minutes of contact time, 30 mg/L chromium (VI) concentration, 2.0 g/L adsorbent part, and 7.0 pH. Further research into the antifungal activity of CMTKG/ZnO nanocomposites against Aspergillus flavus MTCC-2799 was conducted.
