Микромасштабная фронтальная хроматография кобальта(II), никеля(II) и меди(II) на активированном угле, модифицированном фосфатом титана(IV)

Abstract

Concentration dependence of Co2+, Ni2* and Cu2* ions sorption on activated carbon modified by fine titanium phosphate(IV) was investigated. Frontal outlet curves obtained by microscale chromatography were used for determination of capacity and selective sorption characteristics (sorptive capacity, distribution coefficients, separation factors) in the sorbate concentration range 10-3-10-7mol/l. Interfacial distribution coefficients and separation factors increased under reduction of metal concentration in mobile phase. Observed effects were estimated on the assumption of anticooperativity of metal ions transfer in fine titanium phosphate(IV) phase.
