Studying the sorption of Sr and Ni ions from natural water on a ferritized zeolite-containing tuff of the Kholinskoe deposit
Abstract
. The purpose of our study was to assess the sorption properties of a ferritized zeolite-containing tuff (FZCT) of the Kholinskoe deposit (Republic of Buryatia, the Chita region) towards Sr2+ and Ni2+ ions, i.e. elements of different nature, from solutions simulating the mineralisation of natural water. We determined the chemical and physical composition of the studied samples of ZCT and FZCT. Isotherms were obtained for the sorption of Sr2+ from the model solution of drinking water on a natural and ammonium forms of ZCT and FZCT. We also studied the kinetics of sorption of Sr2+ on ZCT and FZCT from the surface drinking water and output curves of Sr2+ from the model solution of artesian water. FZCT appeared to be significantly more effective.
We also investigated the sorption of Ni2+ as an ion having the smallest sorption activity of all the heavy transition metals from a 0.003 n solution of CaCl2 (model solution of drinking water) under equilibrium and non-equilibrium conditions with рН=6.1-6.7. The study demonstrated that under these conditions the sorption of Ni2+ is low and the output curves of Ni2+ are of an external diffusion nature. Apparently, Ni2+ interacts only with ОH-groups of magnetite and its derivatives (maghemite, etc.) under the said conditions. When рН=8.0-8.3, the sorption of Ni2+ increases dramatically.
