A new series of 2-(9-ethyl-9H-carbazol-3-yl)-3-hydroxy-4Hchromen-4-ones have been synthesized from substituted 2-hydroxy acetophenones and 9-ethyl-9H-carbazole-3-carbaldehyde using NaOH and H2O2 by modified Algar-Flynn-Oyamada reaction. In this method flavonols are synthesized without isolating chalcones in good yields (70-82%). The structures of the compounds were established on the basis of 1H-NMR, 13CNMR, FT-IR and mass spectral and analytical data. All the compounds were evaluated for their antimicrobial activity against bacteria such as Staphylococus aureus, Bacillus subtilis, Escherichia

Abstract:
Environmental context Diclofenac, a common non-steroidal anti-inflammatory drug, is not completely removed from surface and drinking water by conventional treatment methods. Consequently, this drug is present in the aquatic environment and has been subsequently linked to toxic effects on organisms. We show that photolysis and TiO2-catalysed degradation in circulating batch reactors efficiently results in diclofenac removal under a variety of conditions. These photochemical methods thus may lead to more effective water treatment processes. Abstract The occurrence of diclofenac (DCF) as an emerg
