硅石支持胶化的 Fe (II )(SiOFe ) 被准备并且在可见照耀下面为 sulforhodamine B (SRB ) 和 2,4-dichlorophenol (DCP ) 的异构的降级使用了(λ 】 420 nm ) 作为有效催化剂。紫外可见的系列,和红外线的 Spectrophotometry,荧光,全部的器官的碳(TOC ) 和电子旋转回声(ESR )( 红外) 大小被采用分析相片产物。结果证明 SRB 能被 SiOFe/H 2 在有在 180 min 照明以后的 100% decolorization 和 72.3% TOC 移动的可见照耀下面的 O 2 系统。ESR 和荧光大小的结果显示氧化进程主要被在系统产生的氢氧根激进分子(· O H ) 支配。
Silica gel-supported Fe(ll) (SiOFe) was prepared and used for heterogeneous degradation of sulforhodamine B (SRB) and 2,4-dichlorophenol (DCP) under visible irradiation (λ 〉 420 nm) as an effective catalyst. UV-visible spectra, and infrared Spectrophotometry (IR), fluorescence, total organic carbon (TOC) and electron spin resonance (ESR) measurements were employed to analyze the photoreaction products. The results showed that SRB could be efficiently degraded by SiOFe/H2O2 system under visible irradiation with 100% decolorization and 72.3% TOC removal after 180 min illumination. The results of ESR and fluorescence measurements indicated that the oxidative process was predominated mainly by the hydroxyl radical (.OH) generated in the system.
