Mineralization of phenol by a Serratia plymuthica strain GC isolated from sludge sample

Pradhan, Nilotpala; Ingle, A.O. (International Biodeterioration & Biodegradation, 60(2), 2007: 103-108)

A bacterial strain isolated from a contaminated soil degraded phenol as the sole source of carbon and energy. It was identified as Serratia plymuthica with the help of its biochemical, physiological and morphological ...
Contrasting REE signatures on manganese ores of iron ore group in north Orissa, India

Mishra, P.P.; Mohapatra, B.K.; Singh, P.P. (Journal Of Rare Earths, 25(6), 2007: 749-758)

The distribution pattern of Rare Earth Elements (REE) in three categories of manganese ores viz. stratiform, stratabound-replacement, and detrital of Precambrian Iron Ore Group from north Orissa, India was reported. These ...
Chromium(VI) removal by calcined bauxite

Baral, S.S.; Das, S.N.; Rath, P.; Chaudhury, G.R. (Biochemical Engineering Journal, 34(1), 2007: 69-75)

The present paper deals with the efficiency of treated bauxite to remove Cr(VI) from a synthetic solution. It includes adsorption of Cr(VI) as a function of contact time, particle size, adsorbent dosage, temperature and ...
Photocatalytic decolorisation of methylene blue (MB) over titania pillared zirconium phosphate (ZrP) and titanium phosphate (TiP) under solar radiation

Das, D.P.; Baliarsingh, N.; Parida, K.M. (Journal Of Molecular Catalysis A-Chemical, 261(2), 2007: 254-261)

The photodegradation of methylene blue (MB) was studied in aqueous solution over titania pillared ZrP and TiP under solar radiation. The reaction was studied by varying different parameters such as pH, titania load, catalyst ...
Studies on heteropoly acid supported zirconia III: Oxidative bromination of phenol using phosphotungstic acid supported on zirconia

Mallik, S.; Parida, K.M.; Dash, S.S. (Journal Of Molecular Catalysis A-Chemical, 261(2), 2007: 172-179)

A series of ecofriendly solid acid catalyst were synthesized by supporting phosphotungstic acid onto hydrous zirconia by an incipient wetness impregnation method in order to contribute towards clean technology. The support ...
Production of eta-alumina from waste aluminium dross

Das, B.R.; Dash, B.; Tripathy, B.C.; Bhattacharya, I.N.; Das, S.C. (Minerals Engineering, 20(3), 2007: 252-258)

Processing of aluminium dross is one of the most challenging tasks because of its toxic nature. The dross generated while melting at various facilities is generally remelted with salts to recover residual metal values. The ...
An overview of utilization of slag and sludge from steel industries

Das, B.; Prakash, S.; Reddy, P.S.R.; Misra, V.N. (Resources Conservation And Recycling, 50(1), 2007: 40-57)

Significant quantities of sludge and slag are generated as waste material or byproduct every day from steel industries. They usually contain considerable quantities of valuable metals and materials. It is generally possible ...
Leaching of manganese ores using sawdust as a reductant

Hariprasad, D.; Dash, B.; Ghosh, M.K.; Anand, S. (Minerals Engineering, 20(14), 2007: 1293-1295)

In this study sawdust was used as reductant for sulphuric acid leaching of manganese ore. Effects of pulp density, amount of acid, temperature, particle size of ore and amount of sawdust were studied. Manganese extraction ...
Mn(III) oxide pillared titanium phosphate (TiP) for catalytic deep oxidation of VOCs

Das, D.P.; Parida, K.M. (Applied Catalysis A-General, 324, 2007: 1-8)

A series of trinuclear acetato complex of Mn(III) intercalated TiP was successfully prepared by ion-exchange process, by varying the wt% of Mn(III) and activated at various temperatures. The calcined and uncalcined samples ...
Structural properties and catalytic oxidation of benzene to phenol over CuO-impregnated mesoporous silica

Parida, K.M.; Rath, D. (Applied Catalysis A-General, 321(2), 2007: 101-108)

A series of copper catalysts supported on mesoporous molecular sieves MCM-41 with copper loading varying from 2 wt% to 10 wt% were synthesized by impregnation method using aqueous copper nitrate solution as the precursor. ...
