Chemical analysis of complex molybdato-phosphates of
rare earth elements with sodium
Abstract
The
molybdato-phosphates of gadolinium and itterbium with sodium Na2Gd(PO4)(MoO4) and Na2Yb(PO4)(MoO4) were obtained
using solid state reactions. Methods for estimation of R3+, Na+, PO43– and MoO42– in synthesized
compounds were investigated. It was
established, that quantitative analysis for these ions is possible without
theirs separations. Analysis of obtained compounds and double gadolinium-sodium
molybdate was carried out. Calculated composition was confirmed.
