Studies of Several Systems with Air Electrode Electro-Synthesizing H2O2 on the Spot for Degrading Aniline in Aqueous

A gas diffusion electrode (air electrode) with a high current efficiency of electro-synthesizing H2O2 using O2 in air was prepared. The several systems with air electrode as cathode of electro-synthesizing H2O2 on the reaction spot for degrading aniline in aqueous--electro-Fenton system, photo-excitation electro-H2O2 system and photo-electro-Fenton system, were developed. The rates of decomposition of H2O2 and mineralization of aniline were experimentally measured respectively under different conditions, and the results indicated there has an excellent parallel relation between decomposition rate of H2O2 and mineralization rate of aniline. Especially, photo-electro-Fenton system, where H2O2 is decomposed the fastest, is the best system of oxidizing and degrading organic toxicants. Compared photo-electro-Fenton system with photo-Fenton system, important role is revealed in the interface of air electrode. In this paper, the mineralization mechanism of aniline in the photo-electro-Fenton system was also discussed.     

流水线用水玻璃砂VRH—CO2法的研究

着重研究了水玻璃砂ＶＲＨ－ＣＯ２法流水线作业时如何调整真空度，ＣＯ２用量和添加剂等，以保证型砂起模的即时强度，同时使０．５～３ｈ的短期存放强度在１ＭＰａ以上，实验结果表明：单纯用真空脱一ＶＲＨ－ＣＯ２法都不能使水玻璃砂的短期存放强度满足流水线生产的要求，只有加入添加剂才可以使ＶＲＨ－ＣＯ２法取得最好的硬化效果，水玻璃模数及ＣＯ２用量都对水玻璃砂短期存放强度有一定影响。
