Photocatalytic Decomposition of Epichlorohydrin by TiO 2 /Ag Coated Sintered Glass Filters

The Application of Sintered (Fritted) Glass Filters to Bacteriological Work.

Glass disks, prepared by sintering finely pulverized glass in a suitable mold (Bruce and Bent, 1931; Kirk, Craig and Rosenfels, 1934; Shatenshtein, 1929) have found applications in the fields of chemistry (Prausnitz, 1924, 1929 and 1932), microchemistry (Kirk, 1933) and pharmacy (Prausnitz, 1930). As far as is known, there is no account in the literature of their employment in bacteriological w...

Improvement in settleability and dewaterability of waste activated sludge by solar photocatalytic treatment in Ag/TiO2-coated glass tubular reactor.

In this study, photocatalysis was used to improve the dewaterability and settleability of waste activated sludge (WAS) by a solar photocatalytic reactor with transparent Ag/TiO2 film as photocatalyst. Specific resistance of filtration (SRF) and sludge volume index (SVI) were used to evaluate WAS dewaterability and settleability, respectively, and the mechanism of photocatalysis was interpreted ...

Bactericidal Activity of Photocatalytic TiO

Additional effects of silver nanoparticles on bactericidal efficiency depend on calcination temperature and dip-coating speed.

There is an increasing interest in the application of photocatalytic properties for disinfection of surfaces, air, and water. Titanium dioxide is widely used as a photocatalyst, and the addition of silver reportedly enhances its bactericidal action. However, the synergy of silver nanoparticles and TiO(2) is not well understood. The photocatalytic elimination of Bacillus atrophaeus was examined ...

Analysis of photocatalytic reactions using a TiO(2) immobilized microreactor.

We have developed an analysis system for photocatalytic reactions, which utilizes a TiO(2) immobilized micro-capillary and a detection technique for dye concentration at arbitrary positions. In this study, we investigated the reaction processes for the photocatalytic decomposition of rhodamine 6G. This system allows the distinction of direct and secondary photocatalytic reactions under the same...

A Semi-Pilot Photocatalytic Rotating Reactor (RFR) with Supported TiO₂/Ag Catalysts for Water Treatment.

A four stage semi-pilot scale RFR reactor with ceramic disks as support for TiO₂ modified with silver particles was developed for the removal of organic pollutants. The design presented in this article is an adaptation of the rotating biological reactors (RBR) and its coupling with the modified catalyst provides additional advantages to designs where a catalyst in suspension is used. The optima...
