A Study of Removal of Ethylbenzene and Xylene Using Biofilter
In the present study, a laboratory scale corn-cob based biofilter inoculated with pseudomonas fluorescents (mtcc 9768) was used for investigating the degradation of ethylbenzene and m-xylene for a period of 60 days in two phases. for ethylbenzene maximum removal efficiency (re) was 72% at an inlet concentration of 4.26 gm -3 and for m-xylene re was 76% at an inlet concentration of 6.39 g m -3 a...
متن کاملDistinction of ortho- and para-xylene by femtosecond-laser mass spectrometry.
The distinction of structural isomers is one of the key tasks in analytical chemistry. In the case where classical electron impact mass spectrometry leads to indistinguishable mass spectra, combined techniques as gas chromatography/mass spectrometry (GC/MS) and so forth can be employed. However, the demand for fast online techniques which circumvent the need for separation is still eminent. One...
متن کاملBacterial metabolism of para- and meta-xylene: oxidation of the aromatic ring.
Pseudomonas putida 39/D oxidized p-xylene to cis-3,6-dimethyl-3,5-cyclohexadiene-1,2-diol (cis-p-xylene dihydrodiol). The latter compound was isolated in crystalline form and its physical properties were determined. The cis configuration of the hydroxyl groups in the oxidation product was inferred from its ability to form an isopropylidene derivative with 2,2-dimethoxypropane. Acid treatment of...
متن کاملNMR Studies of Equilibrium Quotient of the Benzonitrile with Xylene Isomers and Ethylbenzene
The charge transfer (CT) complex formation of benzonitrile as acceptor with the aromatic donors o-, m-, p-xylene and ethylbenzene in CCl4 solutions is investigated by chemical shift measurements relative to an external reference. The equilibrium parameters, Q and DAD of their weak molecular complexes, as found numerically mo...
متن کاملEvaluation of o-xylene and other volatile organic compounds removal using a xylene-acclimated biotrickling filter.
In this study, performance evaluation for the gas-phase o-xylene removal using a xylene-acclimated biotrickling filter (BTF) was conducted. Substrate interactions during aerobic biodegradation of three poorly soluble compounds, both individually and in paired mixtures (namely, o-xylene and ethyl acetate, o-xylene and dichloromethane, which are common solvents used by pharmaceutical industry), w...
