  • Extraction of nickel from ammoniacal solutions using LIX 87QN 
    Sarma, P.V.R.B.; Nathsarma, K.C. (Hydrometallurgy, 42(1), 1996: 83-91)
    Extraction of nickel from ammoniacal-ammonium carbonate solutions using LIX 87QN as the extractant has been studied in detail. The effects of pH (ammonia concentration) and ammonium carbonate concentration on nickel ...
  • Kinetics of Zn2+ adsorption by Penicillium sp. 
    Mishra, S.P.; Chaudhury, G.R. (Hydrometallurgy, 40(1-2), 1996: 11-23)
    Zn2+ ion adsorption studies were carried out using a biomass of Penicillium sp. The percentage adsorption increased with increasing pH and the amount of biomass and showed a reverse trend with temperature and initial Zn2+ ...
  • Investigations on the anomalous oxidation behaviour of high-carbon gas-based direct reduced iron (DRI) 
    Bandopadhyay, A.; Ganguly, A.; Gupta, K.N.; Ray, H.S. (Thermochimica Acta, 276, 1996: 199-207)
    Sponge iron or direct reduced iron (DRI) often shows a tendency to spontaneously combust in a moist oxygen-containing atmosphere. This tendency, however, is different for gas-based DRI compared with coal-based DRI. In this ...
  • Methane budget from paddy fields in India 
    Parashar, D.C.; Mitra, A.P.; Gupta, P.K.; Rai, J.; Sharma, R.C.; Singh, N.; Koul, S.; Ray, H.S.; Das, S.N.; Parida, K.M.; Rao, S.B.; Kanungo, S.P.; Ramasami, T.; Nair, B.U.; Swamy, M.; Singh, G.; Gupta, S.K.; Singh, A.R.; Saikia, B.K.; Barua, A.K.S.; Pathak, M.G.; Iyer, C.S.P.; Gopalakrishnan, M.; Sane, P.V.; Singh, S.N.; Banerjee, R.; Sethunathan, N.; Adhya, T.K.; Rao, V.R.; Palit, P.; Saha, A.K.; Purkait, N.N.; Chaturvedi, G.S.; Sen, S.P.; Sen, M.; Sarkar, B.; Banik, A.; Subbaraya, B.H.; Lal, S.; Venkatramani, S.; Lal, G.; Chaudhary, A.; Sinha, S.K. (Chemosphere, 33(4), 1996: 737-757)
    Results of national methane campaign launched in 1991 to assess methane budget from Indian paddy fields are reported. The campaign involved a number of scientific institutions and universities with National Physical ...
  • Ionic mass transfer studies in fluidized beds with coaxially placed discs on a rod as internal 
    Ravi, T.; Rao, B.S.; Krishna, P.G.; Venkateswarlu, P. (Chemical Engineering And Processing, 35(3), 1996: 187-193)
    Mass transfer data were obtained on the walls of the fluidized beds using an electrochemical technique with a potassium ferri-ferro cyanide couple. The disc promoter assembly was used as internal in fluidized beds, and ...
  • Thermal studies on isolated and purified lignin 
    Rohella, R.S.; Sahoo, N.; Paul, S.C.; Choudhury, S.; Chakravortty, V. (Thermochimica Acta, 287(1), 1996: 131-138)
    The isolation, purification and characterisation of pure lignin, extracted from black liquor obtained from a large pulp and paper mill, are reported. The ultimate analysis of the purified lignin, resulting in 0.3% ash ...
  • Studies on PO4 (3-)/ZrO2 .1. Effect of H3PO4 on textural and acidic properties of ZrO2 
    Parida, K.M.; Pattnayak, P.K. (Journal Of Colloid And Interface Science, 182(2), 1996: 381-387)
    A series of PO43-/ZrO2 samples with PO43- loading in the range 2.24 to 37.5 wt% have been prepared (by impregnation of H3PO4 with Zr(OH)4 and calcination) and characterized by chemical analysis, XRD, FTIR, nitrogen ...
  • Kinetics and mechanism of electroless deposition of copper 
    Mishra, K.G.; Paramguru, R.K. (Journal Of The Electrochemical Society, 143(2), 1996: 510-516)
    This paper describes investigations on the role of electrolyte composition on the mechanism of the electroless copper deposition process. Both potentiostatic and galvanostatic polarization curves as well as steady-state ...
  • Studies on Indian ocean manganese nodules .5. Physicochemical characteristics and catalytic activity of rare earth oxide mixed manganese nodules 
    Parida, K.M.; Sahoo, A.K.; Das, N.N. (Journal Of Colloid And Interface Science, 183(2), 1996: 374-379)
    A series of rare earth oxide mixed manganese nodules (perovskite type mixed oxides) have been prepared by coprecipitation method followed by calcination at 900 degrees C and characterized by different techniques. The effect ...
  • Transition metal oxide pillared clay .1. A comparative study of textural and acidic properties of Fe(III) pillared montmorillonite and pillared acid activated montmorillonite 
    Mishra, T.; Parida, K.M.; Rao, S.B. (Journal Of Colloid And Interface Science, 183(1), 1996: 176-183)
    Fe(III) pillared montmorillonite samples have been prepared by intercalating trinuclear acetato hydroxy-iron (III) nitrate [Fe(COOCH3)(7)OH 2H(2)O](+) NO3- between the layers of both Na-exchanged and acid-activated ...
