1Kinetic and thermodynamic studies of the Co(II) and Ni(II) ions removal from aqueous solutions by Ca-Mg phosphates.

Ivanets AI1, Srivastava V2, Kitikova NV3, Shashkova IL3, Sillanpää M4.

Chemosphere. 2016 Dec 20;171:348-354. doi: 10.1016/j.chemosphere.2016.12.062. [Epub ahead of print]

The aim of this work was to study the sorption kinetics and thermodynamics of Co(II) and Ni(II) from aqueous solutions by sorbents on the basis of hydrogen (PD-1) and tertiary (PD-2) Ca-Mg phosphates depending on the solution temperature and sorbents chemical composition. Kinetic studies of adsorption of Co(II) and Ni(II) ions onto samples of phosphate sorbents were performed in batch experiment at the temperatures 288, 303, 318 and 333 K. Read More
