Description
Summary:Recently, Smičiklas et al. [I. Smičiklas, A. Onjia, S. Raičević, Dj. Janaćković, M. Mitrić, J. Hazard. Mater. 152 (2008) 876–884)] have reported on the effect of pH, contact time, initial metal concentration and presence of common competing cations on hydroxyapatite sorption properties towards Pb 2+, Cd 2+, Zn 2+ and Sr 2+ ions. However, application of some experimental procedures and methods, as well as the presentation and interpretation of some data is problematic or erroneous.
