Photodegradation of selected PCBs in the presence of Nano-TiO2 as catalyst and H2O2 as an oxidant.

Photodegradation of five strategically selected PCBs was carried out in acetonitrile/water 80:20. Quantum chemical calculations reveal that PCBs without any chlorine on ortho-positions are closer to be planar, while PCBs with at least one chlorine atoms at the ortho-positions causes the two benzene rings to be nearly perpendicular. Light-induced degradation of planar PCBs is much slower than the perpendicular ones.

(3S,4R)-4-(4-Fluoro-phen-yl)-3-(hydroxy-meth-yl)piperidinium chloride.

The title compound, C(12)H(17)FNO(+)·Cl(-), is a degradation impurity of paroxetine hydro-chloride hemihydrate (PAXIL), an anti-depressant belonging to the group of drugs called selective serotonin reuptake inhibitors (SSRIs). Similar to the paroxetine hydro-chloride salt with protonation having taken place on the basic piperidine ring, the degradation impurity also exists as the hydro-chloride salt. The cyclic six-membered piperidinium ring adopts a chair conformation with the hydroxy-methyl and 4-fluoro-phenyl groups in the equatorial positions.

Techniques for the evaluation of maturity for composts of industrially contaminated lake sediments.

Composting was applied as a bioremediation methodology for the reclamation of dredged sediments of Isnapur, Khazipally and Gandigudem lakes polluted with industrial wastes. The present study is an attempt to elaborate upon organic matter transformations and define the parameters for product maturity adapting chemical and spectroscopic methods during composting. The stability and maturity of sediments were evaluated by assessing parameters like C/N ratio, nitrification index (NH(4)-N/NO(3)-N), water-soluble organic carbon concentration, CO(2) evolution rate, cation exchange capacity and indices such as humification index, E4/E6 ratio, compost mineralization index (ash content/oxidizable carbon), germination index, dehydrogenase, polyphenoloxidase activities and FTIR spectroscopy.
