Description
  • Adsorption behavior of lead (II) ions on subbituminous coal sample was investigated at temperatures 30 and 60°C. Batch adsorption experiments were used to study the shape of adsorption isotherms as well as the adsorption kinetics. SETARAM C80 calorimeter equipped with mixing vessel was then applied to determine heat effects accompanying the interactions of lead (II) ions with coal surface. As a result, the most significant effect of temperature was ascertained for the kinetics of adsorption process. On the other hand, quite negligible shift in adsorption capacity of coal to Pb(II) ions with temperature was found. Simultaneously, practically no measurable change in enthalpy of adsorption with rising temperature was confirmed. Based on the obtained experimental data, principal thermodynamic parameters concerning adsorption process (e.g. activation energy of adsorption, change in Gibbs energy, ?) were estimated and discussed.

  • Byl studován vliv teploty na adsorpci olova (+II) na hnědém uhlí. Vyšší teplota nemá vliv na adsorpční kapacitu použitého sorbentu. Na druhé straně byl prokázán vliv teploty na kinetiku adsorpčního děje. Na základě kalorimetrických měření byly vypočteny a diskutovány základní termodynamické veličiny. (cs)
