  • Self-organized transformation to polyaniline nanowires by pulsed energetic electron irradiation in a plasma focus device 
    Mohanty, S.R.; Neog, N.K.; Rawat, R.S.; Lee, P.; Nayak, B.B.; Acharya, B.S. (Physics Letters A, 373(22), 2009: 1962-1966)
    An ingenious method for fabricating network of polyaniline nanowires at room temperature in microsecond timescale is demonstrated by using the pulsed electron beam of a plasma focus device. The electron beam of the plasma ...
  • Extraction of cadmium from dilute solution using supported liquid membrane 
    Parhi, P.K.; Das, N.N.; Sarangi, K. (Journal Of Hazardous Materials, 172(2-3), 2009: 773-779)
    The extraction efficiencies of three phosphoric acid derivatives (D2EHPA, PC-88A and Cyanex 272) for Cd in supported liquid membrane (SLM) have been reported. The equilibrium study indicated the release of two moles of ...
  • Studies on sorption of some geomaterials for fluoride removal from aqueous solutions 
    Sujana, M.G.; Pradhan, H.K.; Anand, S. (Journal Of Hazardous Materials, 161(1), 2009: 120-125)
    In the present study the defluoridation capacities of some of the naturally occurring materials like low and high iron containing lateritic ores, overburden from chromite mines of Orissa Mining Corporation (OMC) and Tata ...
  • Removal of Cr(VI) by thermally activated weed Salvinia cucullata in a fixed-bed column 
    Baral, S.S.; Das, N.; Ramulu, T.S.; Sahoo, S.K.; Das, S.N.; Chaudhury, G.R. (Journal Of Hazardous Materials, 161(2-3), 2009: 1427-1435)
    The present study evaluates the feasibility of using a thermally activated fresh water weed in removing Cr(VI) from wastewater through column studies. The effect of flow rate, bed height and Cr(VI) concentration of the ...
  • Sorption behavior of Pb(II) and Cd(II) on iron ore slime and characterization of metal ion loaded sorbent 
    Mohapatra, M.; Rout, K.; Mohapatra, B.K.; Anand, S. (Journal Of Hazardous Materials, 166(2-3), 2009: 1506-1513)
    The present investigation evaluates the sorption effectiveness of Pb(II) and Cd(II) ions on iron ore slime (IOS) obtained from Jindal Steel Ltd., Vijayanagaram, India. The sorption followed pseudo-second-order kinetics for ...
  • Dissolution kinetics of spent petroleum catalyst using sulfur oxidizing acidophilic microorganisms 
    Mishra, D.; Ahn, J.G.; Kim, D.J.; Roychaudhury, G.; Ralph, D.E. (Journal Of Hazardous Materials, 167(1-3), 2009: 1231-1236)
    Bioleaching studies of spent petroleum catalyst were carried out using sulfur oxidizing, Acidithiobacillus species. Leaching studies were carried out in two-stage, in the first stage bacteria were grown and culture filtrate ...
  • Review of fluoride removal from drinking water 
    Mohapatra, M.; Anand, S.; Mishra, B.K.; Giles, D.E.; Singh, P. (Journal Of Environmental Management, 91(1), 2009: 67-77)
    Fluoride in drinking water has a profound effect on teeth and bones. Up to a small level (1-1.5 mg/L) this strengthens the enamel. Concentrations in the range of 1.5-4 mg/L result in dental fluorosis whereas with prolonged ...
  • Microbial recovery of uranium using native fungal strains 
    Mishra, A.; Pradhan, Nilotpala; Kar, R.N.; Sukla, L.B.; Mishra, B.K. (Hydrometallurgy, 95(1-2), 2009: 175-177)
    Native microorganisms were isolated from water samples collected from uranium mines of Jaduguda, Bhatin and Nawapahar of UCIL India. Ten fungal strains isolated in pure cultures were selected, identified and used in this ...
  • Application of liquid/solid fluidization technique in beneficiation of fines 
    Mukherjee, A.K.; Mishra, B.K.; Kumar, R.V. (International Journal Of Mineral Processing, 92(1-2), 2009: 67-73)
    Use of liquid/solid fluidization techniques for size classification is a common practice in mineral processing operations. Extending its application in gravity separation for finer feed particles (-0.5 mm) is not straightforward ...
  • Dissolution kinetics of spent petroleum catalyst using two different acidophiles 
    Pradhan, D.; Mishra, D.; Kim, D.J.; Chaudhury, G.R.; Lee, S.W. (Hydrometallurgy, 99(3-4), 2009: 157-162)
    Leaching studies using spent petroleum catalyst containing Ni, V and Mo were carried out using two different acidophiles, iron oxidizing (IOB) and sulfur oxidizing (SOB) bacteria. XRD analysis proved the existence of V in ...
