Copperphthalocyanine immobilized Zn/Al LDH as photocatalyst under solar radiation for decolorization of methylene blue

Parida, K.M.; Baliarsingh, N.; Patra, B.S.; Das, J. (Journal Of Molecular Catalysis A-Chemical, 267(1-2), 2007: 202-208)

Zn/Al hydrotalcite-like compounds (HTlcs) with Zn/Al molar ratios of 2:1, 3:1, 4:1 were synthesized by co-precipitation method and were used as supports for the immobilization of Cu(II) tetrasulphonated phthalocyanine ...
Silicotungstic acid supported zirconia: An effective catalyst for esterification reaction

Parida, K.M.; Mallick, S. (Journal Of Molecular Catalysis A-Chemical, 275(1-2), 2007: 77-83)

A series of solid acid catalysts were synthesized by incipient wetness impregnation method by varying the wt% of silicotungstic acid on hydrous zirconia (ZSTA). The prepared catalysts were characterized by PXRD, FTIR, ...
Esterification of acetic acid with n-butanol over manganese nodule leached residue

Dash, S.S.; Parida, K.M. (Journal Of Molecular Catalysis A-Chemical, 266(1-2), 2007: 88-92)

Manganese nodule leached residue (MNLR) was obtained as waste material after selective extraction of Cu, Co and Ni from Indian Ocean manganese nodule. MNLR was washed with water to remove sulphate and other impurities ...

Sarangi, K.; Parhi, P.K.; Padhan, E.; Palai, A.K.; Nathsarma, K.C.; Park, K.H. (Separation And Purification Technology, 55(1), 2007: 44-49)

Separation of iron(III), copper(II) and zinc(II) from a mixed sulphate/chloride leach liquor bearing 11.8 kg/m(3) iron, 24.8 kg/m(3) copper, 0.23 kg/m(3) zinc, 3.8 kg/m(3) cobalt, 35.2 kg/m(3) nickel, 176.3 kg/m(3) chloride ...
Fe(III) oxide pillared titanium phosphate (TiP): An effective catalyst for deep oxidation of VOCs

Das, D.P.; Parida, K.M. (Journal Of Molecular Catalysis A-Chemical, 276(1-2), 2007: 17-23)

A series of trinuclear acetato complex of Fe(Ill) intercalated TiP was successfully prepared by ion exchange process by varying the wt% of Fe(Ill), activated at various temperatures and characterized by various techniques. ...
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 ...
