| Abstract: | A method is proposed for the synthesis of silicic acid xerogels based on opoka aluminosilicate (gaize) and silicate glue. The physicochemical properties of xerogels were studied. The complexation of Be(II) with immobilized Chrome Azurol S was studied by electronic absorption and diffuse-reflection spectrometry and solid-phase spectrophotometry. Test procedures were developed for determining Be(II) and Al(III) in waters and soils. |
