Аннотация: Novel silica-based adsorption materials layer-by-layer modified with polyhexamethylene guanidine and Arsenazo I or Arsenazo III have been proposed for solid-phase extraction of rare earth elements (REE). Silica, modified with Arsenazo I, quantitatively extracted REE at pH 5.5 - 7.0, and silica, modified with Arsenazo III, at pH 2.0Показать полностью-6.0 with distribution coefficients of 2.9 center dot 10(3)-4.6 center dot 10(4) cm(3) g(-1). The adsorption capacity for REE was 1.25-2.85 mg g(-1). Silica, layer-by-layer modified with polyhexamethylene guanidine and Arsenazo III, was used for removal of REE from solutions after digestion of lignites and ashes after their burning.
