Abstract
Processes and products of ion exchange of günterblassite (K,Ca,Ba,Na)3–xFe1–y[(Si,Al)13O25(OH,O)4]·7H2O (microporous silicate, structurally intermediate between smectites and zeolites) and three samples of zeolite gmelinite (Na,K,Ca,Mg)x[(Si,Al)12O24)·nH2O of different composition with cations of various metals were studied. It was shown that günterblassite exhibits high activity and sorption capacity with respect to Rb+, Cs+, Ag+ cations and, to a lesser extent, Pb2+ and Ba2+: even at room temperature for 1 h, the concentration of M2O (M = Rb, Cs, Ag) in the sorbent reaches 10–13 wt %. The ion exchange in gmelinite occurs according to the frontal mechanism, propagating from the periphery of the crystal to its center. In reactions with Pb2+, the activity of gmelinite increases with a rise in its sodium content and decreases with a rise in potassium content. The crystal structure of Pb-substituted gmelinite was studied and it was shown that Pb2+ ions populate both zeolite channels. Synthetic gmelinite obtained from cheap natural raw materials and fly ash from thermal power plants can be used to purify water from lead.
