摘要

本文介绍了在不同类型的封端剂（海藻酸钠、聚乙烯醇、聚乙烯吡咯烷酮）中使用等离子液体放电 AgNO3 溶液一步合成银纳米粒子（Ag NPs）的方法。利用透射电子显微镜（TEM）、X 射线衍射（XRD）和紫外-可见（UV-Vis）吸收光谱对纳米粒子进行了表征。研究了银离子浓度和封端剂等反应条件对 AgNPs 合成的影响。合成了银纳米粒子-海藻酸盐复合珠，作为饮用水消毒填料柱的填充材料。研究发现，使用不同类型的封端剂制备的复合微珠对大肠杆菌的消毒效果各不相同。

One-pot Synthesis of Silver Nanoparticles and Composite Materials for Drinking Water Disinfection

This paper presents one-step approach for synthesis of silver nanoparticles (Ag NPs) using plasma liquid discharge AgNO3solutions in present different type capping agents: sodium alginate, polyvinyl alcohol, polyvinyl pyrrolidone. The nanoparticles were characterized using transmission electron microscopy (TEM), X-ray diffraction (XRD), ultraviolet-visible (UV-Vis) absorption spectroscopy. The effect of reaction conditions such as the concentration of silver ions and capping agent on the synthesis of AgNPs was studied. Silver nanoparticles -alginate composite beads were synthesized as filler materials of packed columns for drinking water disinfection. Composite beads prepared using different type capping agents were found to be effective in disinfecting the E. coli to different extents.
