  • Wet chemical synthesis of low bulk density aluminium hydroxide powder 
    Pradhan, J.K.; Gochhayat, P.K.; Bhattacharya, I.N.; Das, S.C.; Panda, R.K. (Journal Of Chemical Technology And Biotechnology, 78(5), 2003: 577-581)
    Fine, low bulk density aluminium hydroxide powdered gel was prepared by the mild base hydrolysis of an aqueous solution of aluminium sulfate with hydrazine hydrate. Parameters such as method of addition of reactant, initial ...
  • Extraction and composition of the essential oil of ambrette (Abelmoschus moschtus) seeds 
    Rout, P.K.; Rao, Y.R.; Jena, K.S.; Sahoo, D.; Mishra, B.C. (Journal Of Essential Oil Research, 16(1), 2004: 35-37)
    Selective extraction with methanol of uncrushed ambrette seeds grown in India and liquid-liquid extraction of the residue afforded a volatile concentrate in 0.33% yield free from the fatty acids and off-notes associated ...
  • Essential oils of leaves of Curcuma species 
    Behura, S.; Srivastava, V.K. (Journal Of Essential Oil Research, 16(2), 2004: 109-110)
    The leaf oils of Curcuma caesia Roxb. and two cultivars of C. longa L. were investigated by GC. The leaf oils can be characterized by the following major constituents C. longa 'Roma': terpinolene (87.8%); C. longa 'Kasturi': ...
  • Sorption of arsenate from aqueous solution with manganic ferric oxyhydroxide 
    Chaudhury, G.R.; Chattopadhyay, P.; Das, R.P.; Muir, D.M.; Singh, P. (Hydrometallurgy 2003 Proceedings, Vols 1 And 2: Vol 1: Learning And Solution Purification - Vol 2: Electrometallurgy And Environmental Hydrometallurgy, 2003: 1913-1922)
    Adsorption techniques are comparatively low cost and effective for treatment of arsenic contaminated drinking water. Various adsorbents such as alumina, ferrihydrite and manganese ores have been used, but there has been ...
  • Electrocrystallisation of nickel: Effect of certain metal ions 
    Tripathy, B.C.; Mohanty, U.S.; Subbaiah, T.; Das, S.C.; Misra, V.N. (Hydrometallurgy 2003 Proceedings, Vols 1 And 2: Vol 1: Learning And Solution Purification - Vol 2: Electrometallurgy And Environmental Hydrometallurgy, 2003: 1247-1253)
    The effects of alkali metal ions Li+, Na+, K+ and transition metal ions Cr3+ and Mo6+ on the cathodic current efficiency, deposit quality, crystallographic orientations, deposit morphology and polarisation behaviour of the ...
  • Cathodic deposition of copper in the presence of aqueous sulfurous acid, bivalent aquacobalt ion, or both using a stainless steel cathode and a graphite anode 
    Panda, B.; Das, S.C.; Panda, R.K. (Metallurgical And Materials Transactions B-Process Metallurgy And Materials Processing Science, 34(6), 2003: 813-819)
    A study on cathodic deposition of copper in acidic aqueous sulfate solution has been carried out using a stainless steel cathode and a graphite anode. The individual and the combined effects of added [H(2)SO(3)(.)aq] and ...
  • Synthesis of value added products from pickle liquor and their physico-chemical characterization 
    Nayak, R.; Rao, J.R. (Journal Of Scientific & Industrial Research, 62(10), 2003: 1015-1019)
    Aqueous suspensions of gelatinous precipitates were prepared by mixing solutions of sodium carbonate with iron(II) sulphate, a waste obtained from steel plants, in the ratio Of CO32-/SO42->1. These were subjected to ...
  • Impact of wastewater discharge on soil and ground water - A case study 
    Das, R.; Das, S.N. (Journal Of Scientific & Industrial Research, 62(3), 2003: 207-211)
    The paper reports the analysis of effluents released from different sources and characteristics of soil/ground water nearer to the source of contamination. In a case study the areas selected for investigation comprise a ...
  • Chemical oxidation of spent cathode carbon blocks of aluminium smelter plants for removal of contaminants and recovery of graphite value 
    Mazumder, B. (Journal Of Scientific & Industrial Research, 62(12), 2003: 1181-1183)
    Used carbon cathode blocks (also known as spent pot liners) are discarded by aluminium smelting plants in large quantities and because of their high contamination of fluoride, its disposal to open ground pose considerable ...
  • Ferrous-ferric oxidation in pickle liquor 
    Nayak, R.; Rao, J.R. (Journal Of Scientific & Industrial Research, 62(11), 2003: 1094-1097)
    Pickle liquor, a waste from metallurgical industries and containing iron(II) sulphate in crude form, has been subjected to oxidation studies. Oxidation of aqueous iron from Fe(II) to Fe(III) in different alkali media has ...
