adsorption and desorption behavior of gd(iii) ionon macroporous weak acid resin (mwar) had been investigated.the influence of operational conditions such as contact time, initial concentration of gd(iii) ion, initial ph of solution and temperature on the adsorption of gd(iii) ion had been examined. experimental data were exploited for kinetic and thermodynamic evaluations related to the adsorpt...

The objective of this study was to assess the adsorption potential of activated carbon (AC) asan adsorbent for the removal of Murexide (Mu) from aqueous solutions. The influence of variablesparameters including pH, amount of adsorbent, sieve size of adsorbent, temperature and contact timeon Mu removal was studied. Following optimization of variables, the relation between concentrations ofdye re...

The present study aims at investigating the potential of activated carbon AC prepared from waste cotton fiber for the removal of Acid Dyes from aqueous solutions. The prepared activated carbon was characterized by pore structure analysis, Fourier transforms infrared spectroscopy FTIR. Batch adsorption studies were carried out and the effect of experimental parameters such as pH, initial dye con...

AlMCM-41 was applied for adsorption of methylene blue (MB) and auramine (AU) in single and binary component systems. In the single component systems, AlMCM-41 represents higher adsorption capacity for MB than AU with the maximal adsorption capacity of 2.07×10−4 and 1.15×10−4 mol/g at 25 ˚C for MB and AU, respectively. In the binary component system, MB and AU exhibit compe...

The kinetic equation used to predict the current being passed in an intercalation electrode depends on the overpotential and the composition of the intercalating species. The overpotential depends on the difference between the potential in the solid phase and in the solution phase, both of which depend on the composition of the intercalation species in the solid and solution phases, respectivel...

biosorption of two anionic dyes, eosin y and eosin b, from aqueous solution using saccharomyces cerevisiae was investigated in a batch mode. the influence process parameters such as contact time, initial dye concentration, sorbent dosage, ph and temperature of aqueous solution were studied. the maximum adsorption capacities were found to be at 200 and 100 mg g-1 for eosin y and 1 eosin b, respe...

A nonequilibrium thermodynamic theory demonstrating an induction effect of a statistical nature is presented. We have shown that this thermodynamic induction can arise in a class of systems that have variable kinetic coefficients (VKC). In particular if a kinetic coefficient associated with a given thermodynamic variable depends on another thermodynamic variable then we have derived an expressi...

For the free Fermion gas at thermodynamic equilibrium, the temperature which represents the averaged kinetic energy is demonstrated to have the proper property which is invariant under the Lorentz boost, using the conceptions of the relativistic quantum field theory and statistical physics. The thermodynamic interaction is described by the coupling of particles with the vacuum of a scalar pseud...
