Initial leaching of the material results in the removal of soluble anionic alkalinity (HC[O.sub.3.sup.-], C[O.sub.3.sup.2-], or Al[(OH).sub.4.sup.-]) as counterions for the major cation present ([Na.sup.+]) and, therefore, a decrease in residue pH (Jones et al.
Based on the variety of experimental procedures reported or producing MOF-199 and the absence of information in literature concerning the importance of understanding the significant experimental conditions for MOF-199 production, the aim of this work was to apply a [2.sup.3] factorial design to evaluate the influence of [Cu.sup.2+] salts counterions, acetate (OAc) and chloride ([Cl.sup.-]), and the synthesis parameters (time, temperature and metal concentration) on the reaction yield (response variable) of MOF-199.The obtained compounds were characterized by infrared vibrational spectroscopy (FT-IR spectroscopy), thermogravimetric analysis (TGA) and powder X-ray diffraction (XRD).
We first consider binary electrolyte solutions with equal and different counterion and co-ion sizes and compare the obtained results with those obtained using the Carnahan-Starling theory.
