EQUILIBRIUM AND THERMODYNAMICS OF AZO DYES BIOSORPTION ONTO Spirulina platensis
The equilibrium and thermodynamics of azo dye (tartrazine and allura red) biosorption onto Spirulina platensis biomass were investigated. The equilibrium curves were obtained at 298, 308, 318 and 328 K, and four isotherm models were fitted the experimental data. Biosorption thermodynamic parameters (ΔG, ΔH and ΔS) were estimated. The results showed that the biosorption was favored by a temperat...
متن کاملEquilibrium, thermodynamic and kinetic studies for the biosorption of aqueous lead(II), cadmium(II) and nickel(II) ions on Spirulina platensis.
The biosorption of lead(II), cadmium(II) and nickel(II) ions from aqueous solution by Spirulina platensis was studied as a function of time, concentration, temperature, repetitive reactivity, and ionic competition. The kinetic results obeyed well the pseudo second-order model. Freundlich, Dubinin Radushkevich and Temkin isotherm models were applied in describing the equilibrium partition of the...
متن کاملCyanobacteria Spirulina Platensis Basic Protein C-Phycocyanin and Zn(II) Ions
The interaction of Zn(II) ions with cyanobacteria Spirulina platensis basic protein C-phycocyanin (C-PC) is studied by fluorescence spectroscopy.Stern–Volmer quenching constant value for Zn(II)–C-PC is determined. The binding energy of Zn(II) ions with C-phycocyanin is determined using equilibrium dialysis and atomic absorption spectroscopy. Cooperative binding of Zn(II) ions with C-phycocyanin...
متن کاملthe efficiency of lead biosorption from industrial wastewater by micro-alga spirulina platensis
environment contamination by heavy metals is a major issue threatening human health. adsorption is one of the biological processes for removing toxic metals from wastewater. the aim of this study was to determine the rate of lead biosorption from industrial wastewater by spirulina platensis. this laboratory scale experimental study was performed during april 2014 to october 2014 in environmenta...
متن کاملChromium Biosorption from Cr(VI) Aqueous Solutions by Cupressus lusitanica Bark: Kinetics, Equilibrium and Thermodynamic Studies
The present study investigated the kinetics, equilibrium and thermodynamics of chromium (Cr) ion biosorption from Cr(VI) aqueous solutions by Cupressus lusitanica bark (CLB). CLB total Cr biosorption capacity strongly depended on operating variables such as initial Cr(VI) concentration and contact time: as these variables rose, total Cr biosorption capacity increased significantly. Total Cr bio...
