在此,在存在侧柏叶(Cacumen Platycladi)(C.考察了不同工艺参数(体积流量、浓度、pH值、pH值)对提取率的影响。侧柏提取物、入口混合模式)和反应器参数(反应器材料和内径)对AgNP的尺寸分布的影响。利用计算流体力学(CFD)模拟了微反应器内的速度、生物质浓度和温度分布。结果表明,与传统的本体反应器不同,微反应器中固体表面与本体溶液之间的界面效应不可忽视,并对颗粒的粒径分布有重要影响。CFD模拟结果证实了微通道具有一些独特的流动特性,不同的工艺参数对AgNPs的粒径分布有特定的影响,这可以从它们对界面效应和流动特性的影响来解释。我们的工作提供了有益的洞察微流控生物合成的过程参数对AgNPs的尺寸分布的影响。
Here, microfluidic biosynthesis of Ag nanoparticles (AgNPs) in tubular microreactors in the presence of Cacumen Platycladi (C. Platycladi) extract was studied, focusing on the effect of technical parameters (volumetric flow rate, the concentration of C. Platycladi extract, inlet mixing pattern) and reactor parameters (reactor materials and inner diameter) on the size distribution of AgNPs. Computational fluid dynamics (CFD) was utilized to simulate the profile evolution of velocity, biomass concentration and temperature in the microreactors. It was found that, unlike in traditional bulk reactors, the interfacial effect between the solid surface and bulk solutions in microreactors could not be ignored and had crucial influence on particle size distribution. Results of CFD simulation confirmed that microchannels possessed some unique flow characteristics and various process parameters had specific influences on the size distribution of the AgNPs, which could be explained in terms of their influences on the interfacial effect and flow characteristics. Our work provides useful insight into the influence of process parameters on size distribution of AgNPs in microfluidic biosynthesis.
