The role of external and internal mass transfer in the process of Cu2+removal by natural mineral sorbents
(Environmental Technology, 2011)
The kinetics of Cu2+ sorption on to zeolite, clay and diatomite was investigated as a function of initial metal concentrations. For consideration of the mass transfer phenomena, single resistance models based on both film ...
Analysis and comparison of mass transfer phenomena related to Cu2+ sorption by hydroxyapatite and zeolite
(Chemical Engineering Journal, 2013)
Zeolite and hydroxyapatite (HAP) are well-known sorbent materials, with high capacities for removal of toxic heavy metals. In this study, the influence of process parameters onto kinetics of Cu2+ sorption by zeolite and ...
The influence of equilibration conditions and hydroxyapatite physico-chemical properties onto retention of Cu2+ ions
(Chemical Engineering Journal, 2009)
The influence of equilibration conditions and hydroxyapatite (HAP) physico-chemical properties onto retention of Cu2+ ions was studied in batch conditions. The amount of cation removed from the solution increased with ...
