HPTLC Method for Quantitative Evaluation of Preparations Containing Indian 'Elixir' Plant, Tinospora cordifolia, Using Jatrorrhizine as Marker

Mallavadhani, U.V.; Sahu, G. (Jpc-Journal Of Planar Chromatography-Modern Tlc, 22(6), 2009: 439-443)

Because of its extensive use in traditional medicine, the Indian plant T. cordifolia, known as 'Heavenly Elixir', has been chemically and analytically screened. Because the stem is therapeutically highly valued, its methanol ...
A compilation and critical evaluation of the literature data on thermal dehydration of hydrated salts

Kanungo, S.B. (Journal Of The Indian Chemical Society, 86(7), 2009: 679-689)

The article provides a detailed compilation of literature data on the thermal dehydration of simple (formed from single cation and anion) hydrated salts consisting of a wide variety of cations and anions or ligands. An ...
Adsorption of Pb(II) Ions from Aqueous Solutions Using a Low Grade Iron Ore as an Effective Adsorbent

Dash, B.; Das, B. (Adsorption Science & Technology, 27(5), 2009: 479-491)

The use of banded hematite quartzite (BHQ), a low-grade iron ore, as an adsorbent for the removal of lead(II) ions from aqueous solutions was studied. X-Ray diffraction (XRD) studies of BHQ ore showed the presence of ...
Occurrence and distribution of bacterial indicators and pathogens in coastal waters of Orissa

Patra, A.K.; Acharya, B.C.; Mohapatra, A. (Indian Journal Of Marine Sciences, 38(4), 2009: 474-480)

Bacterial population in the coastal water of Orissa, up to 10 km from shoreline along 6 transects were observed during 2005-06 and 2006-07. Total viable counts (TVC), total coliforms (TC), faecal coliforms (FC), faecal ...
Adsorption behaviour of Pb(II), Cd(II) and Zn(II) on NALCO plant sand

Mohapatra, M.; Khatun, S.; Anand, S. (Indian Journal Of Chemical Technology, 16(4), 2009: 291-300)

Present investigation evaluates the adsorption of Pb(II), Cd(II) and Zn(II) ions on plant sand of National Aluminum Company, Orissa, India. The XRD pattern and FTIR spectra showed goethite, alumina and silica as the major ...
Seasonal variations of phytoplankton in Mahanadi estuary, east coast of India

Naik, S.; Acharya, B.C.; Mohapatra, A. (Indian Journal Of Marine Sciences, 38(2), 2009: 184-190)

Seasonal variations of phytoplankton and chlorophyll-a along with its environmental variations including nutrients were studied from June-2004 to March-2007. Samples were collected in three different seasons pre-monsoon ...
Effect of thermal annealing on the structure and microstructure of TiO2 thin films

Rath, H.; Anand, S.; Mohapatra, M.; Dash, P.; Som, T.; Singh, U.P.; Mishra, N.C. (Indian Journal Of Physics, 83(4), 2009: 559-565)

Nanostructured TiO2 thin films have been prepared through chemical route using sol-gel and spin coating techniques. The deposited films were annealed in the temperature range 400-1000 degrees C for 1 h. The structure and ...
ENERGY AND SUSTAINABLE DEVELOPMENT IN HYDROMETALLURGY - AN EMERGING PERSPECTIVE

Rao, K.S. (Energy Technology Perspectives: Conservation, Carbon Dioxide Reduction And Production From Alternative Sources, 2009: 195-200)

Any innovative approach made in non-ferrous metallurgical industry centers upon developing new processes, saving materials, improving production quality, and born-again materials. Aqueous processing is commonly used to ...
Bioleaching of Complex Sulfides Concentrate and Correlation of Leaching Parameters Using Multivariate Data Analysis Technique

Kim, D.J.; Pradhan, D.; Chaudhury, G.R.; Ahn, J.G.; Lee, S.W. (Materials Transactions, 50(9), 2009: 2318-2322)

Bacterial leaching was applied to recover metal values from complex sulfide concentrates. The leaching kinetics were observed to depend on various leaching parameters. including Fe(II) concentration, pH and pulp density. ...
MICROBIAL REDUCTION OF LATERITIC NICKEL ORE, FOR ENHANCED RECOVERY OF NICKEL AND COBALT THROUGH BIOHYDROMETALLURGICAL ROUTE

Sukla, L.B.; Mishra, B.K.; Pradhan, Nilotpala; Mohapatra, R.K.; Mohapatra, B.K.; Nayak, B.D. (Energy Technology Perspectives: Conservation, Carbon Dioxide Reduction And Production From Alternative Sources, 2009: 213-224)

Present study is about use of a group of Iron[Fe(III)] Reducing Bacteria (IRB) to convert the goethite (alpha-FeOOH) present in the original lateritic Nickel ore to magnetite under an anaerobic condition and subsequently ...
