Abstract

The process of precipitation of La3+, Sm3+ and Tb3+ ions by anionic surfactant alkylbenzenesulfonic acid at various concentrations and ratios of components has been studied. The influence of the medium acidity and mixing time on the precipitation is considered. The resulting precipitates of REE ions with alkylbenzenesulfonic acid were studied by thermogravimetric, elemental and chemical analysis, and their composition was established. The conditional solubility products of the formed precipitates have been calculated. The optimal conditions for the precipitation of lanthanum (III), samarium (III) and terbium (III) ions with alkylbenzenesulfonic acid from aqueous solutions have been established.
