Bisphenol A Mineralization by Integrated Ultrasound-UV-Iron (II) Treatment

Aqueous Quinoline Treatment with Iron/ Copper Activated UV/ Persulfate Process in a Falling Film Photo-Reactor

S2O8/UV-C and H2O2/UV-C TREATMENT OF AQUEOUS BISPHENOL A RESULTS IN DIFFERENT ACUTE TOXICITY PATTERNS

Bisphenol A (2,2-bis(4-hydroxyphenyl)propane), a chemical compound used in the manufacture of polycarbonate, epoxy and polysulfonate resins, can alter the endocrine system, causing adverse effects in the reproductive systems of humans and animals. More recently, the application of advanced oxidation processes (AOPs) has been recommended to treat toxic and/or biorefractory compounds including BP...

Biologically Controlled Mineralization of Magnetic Iron Minerals by Magnetotactic Bacteria

The biomineralization of several magnetic iron minerals, including the iron oxide magnetite (Fe30 4 ; Fe 2I Fe/+04 ) and the iron sulfides greigite (Fe3S4 ) and pyrrhotite (Fe7SS)' can be mediated by bacteria as well as by other organisms. These minerals are known to be synthesized by procaryotes in one of two fundamentally different modes of biomineralization. The first is uncontrolled mineral...

Photocatalytic Degradation of Bisphenol A from Aqueous Solutions using TiO2 Nanoparticles and UV Illumination

Background and Purpose: Bisphenol A (BPA) is used to make certain plastics and epoxy resins. It is a non-biodegradable compound, and poses health risks to both humans and animals. The purpose of this study was to evaluate decomposition efficiency of BPA from aqueous solutions using UV irradiation. Materials and Methods: In this study, the photodegradation of BPA in water were carrie...

Thermal UV treatment on SU-8 polymer for integrated optics

We report a simple and low-cost method to fabricate SU-8-based polymer waveguide devices. The influence of hard-baking temperature on SU-8 polymer treated with or without UV radiation was investigated in detail. Based on these properties, the straight type, Y branch type, MarchZehnder (M-Z) type and 1 × 4 splitter waveguides were successfully fabricated. And a polymeric thermal-optic (TO) switc...
