  • Biosorption of monovalent and divalent ions on baker's yeast 

    Vasudevan, Padma; Padmavathy, V; Dhingra, S C (2002)
    Biosorption of monovalent ions Na+ and K+, by deactivated protonated yeast (Saccharomyces cerevisiae) at controlled pH, was compared with biosorption of divalent ions Ca2+ and Mg2+ to help to understand the underlying ...
  • Biosorption of nickel(II) ions on Baker's yeast 

    Padmavathy, V; Vasudevan, P; Dhingra, S C (2003)
    The biosorption of nickel(II) ions by deactivated protonated yeast was investigated with respect to the initial pH and initial metal ion concentration. The kinetics of sorption was also followed based on the amounts of ...
  • Kinetics of biosorption of cadmium on Baker’s yeast 

    Vasudevan, Padma; Padmavathy, V; Dhingra, S C (2003)
    In the present study the kinetics of biosorption of cadmium(II) ions by deactivated protonated yeast converted to sodium form was investigated for different initial concentrations of the metal ion (10–100 ppm) and different ...
  • Thermal and spectroscopic studies on sorption of nickel(II) ion on protonated baker’s yeast 

    Padmavathy, V; Vasudevan, Padma; Dhingra, S C (2003)
    Protonated form (Hy) of yeast was subjected to thermal analysis (TGA and DTG) in the temperature range 60–800 °C. Chemically bound water volatilizes around 200 °C and the matrix undergoes extensive oxidative decomposition ...
