In this research the polymer which contains aldehyde group [H1] has been prepared by oxidation [H] using oxidizing agent (Dess Martin Periodinane), dialyzed ethanol, Schiff bases[H2,H5andH8] compounds have through reaction of compound with appropriate amines, [H3] hydroquinazolin ring [H2] 2-amino benzoic acid.[H4]which cyclization phthalic anhydride. [H6,H7]were [H5] acid and anhydriede. React...

Considering the nature of organic contaminants in water, methods their oxidative decomposition seem to be most appropriate for removal from contaminated water. There are a lot chemical oxidation, however, Advanced Oxidation Processes (AOPs) suitable technologies removal. AOPs belong group processes that efficiently oxidize compounds towards harmless inorganic products such as water or carbon di...

AIMS Oxidizing agents such as chlorine dioxide are widely used microbicides, including for disinfection of medical equipment. We isolated a Bacillus subtilis isolate from a washer-disinfector whose vegetative form demonstrated unique resistance to chlorine dioxide (0·03%) and hydrogen peroxide (7·5%). The aim of this study was to understand the mechanisms of resistance expressed by this isolate...

Over the years, there has been an increase in consumption of drugs, particularly antibiotics. Amoxicillin (AMX) is considered one most widely used antibiotics, causing resistance microorganisms ecosystem where it found. Additionally, cataloged among drugs under surveillance by European Commission since 2020. The present work studies efficiency AMX degradation photolysis and heterogeneous solar ...

We investigated the in situ spatial organization of ammonia-oxidizing and nitrite-oxidizing bacteria in domestic wastewater biofilms and autotrophic nitrifying biofilms by using microsensors and fluorescent in situ hybridization (FISH) performed with 16S rRNA-targeted oligonucleotide probes. The combination of these techniques made it possible to relate in situ microbial activity directly to th...

In most of the oxidation—reduction reactions involving net electron transfer which have been studied, the experimental results yield only second order rates, and thus reflect the barrier to bringing reactants together as well as that for the electron transfer act itself. Recent advances in synthetic procedures make it possible to measure as an intramolecular or first order process, net electron...
