Sorption of Heavy Metal Ions from Water by Natural Apatite Ore

The article shows the efficient use of natural apatite ore in purification of mining industrial wastewaters from heavy metal ions. The determination of adsorption constants, calculation of thermodynamic parameters at various pH of the medium were carried out. It was established that the sorbent based on apatite ore may be used in ecological and technological aims in water conditioning and water treatment.

Tracer Chromatographic Adsorption Studies in Relation to Liquid-Phase Catalysis

The hydrophobic or hydrophilic properties of solid catalysts often have a crucial influence on their properties in liquid-phase catalytic reactions. Several methods to measure liquid-phase adsorption on catalytic solids are compared, and special attention is given to the liquid chromatographic method. The experimental setup and the determination of adsorption constants are discussed. Finally, adsorption data measured via the chromatographic method are used to gain insight into liquid-phase catalytic reactions, particularly oxidations with Ti zeolites.
