Аннотация
The synthesis scheme and properties of folates with compositions Li2C19H17N7O6 ∙ 5H2O, PbC19H17N7O6 ∙ 4H2O, CdC19H17N7O6 · 4H2O, and Eu2(C19H17N7O6)3 · 12H2O are described. The solubility constants KS are determined for lead(II), cadmium, europium(III) and folic acid C19H19N7O6 · 2H2O at an ionic strength I = 0.1. The contemplations on using soluble europium(III) salts to extract folic acid from solutions at pH ~6 in the form of poorly soluble europium folate (logKS = –24.68 ± 0.11), followed by regeneration of folic acid (by 99%) in an acidic medium, and on using folic acid or soluble sodium folate as an antidote of lead poisoning are presented.
