摘要
通过掺硅纳米α-FeOOH絮凝剂在水处理应用中的形态表征试验和吸附性能试验,研究了反应的控制因素对絮凝剂表面特性、形貌、粒径和吸附性能的影响。研究表明,不同掺比的掺硅纳米α-FeOOH的形貌、粒径分布达到纳米级别,且对持久性有机污染物PFOS都有较高的去除率;掺硅纳米α-FeOOH的投加量、pH值、溶液盐度对其吸附PFOS产生影响,Si/Fe值为0.01的掺硅纳米α-FeOOH的净化效果最好。
Through the morphological characterization test and adsorption performance test of silicon-doped nano-α-FeOOH flocculant in water treatment, the influence of control factors on the flocculant surface characteristics, morphology, particle size and adsorption performance was studied. The research shows that the morphology and particle size distribution of silicon-doped nano-α-Fe00H with different proportions reach the nanometer level, and they have higher removal rates for PFOS. The dosage of the flocculant, pH and salinity affect the adsorption of PFOS. When the ratio of Si/Fe is 0.01, the adsorption efficiency of silicon-doped nano-α-FeOOH is the best.
