Synthesis of sorption materials based on dithiooxamidate aminopropyl polysiloxane

Synthesis of sorption materials based on dithiooxamidate aminopropyl polysiloxane Reaction of reamidation of rubeanic acid with aminopropyl polysiloxane was systematically studied. It was found that the given type of transformations make it possible to obtain a derivative of aminopropyl polysiloxane with surface dithiooxamide groups in a concentration of up to 0.78 mmol g−1 at a total degree of substitution of up to 0.25. The composition and structure of the derivatives obtained were characterized by elemental analysis, IR spectroscopy, thermogravimetry, and method of low-temperature adsorption of nitrogen. The sorption of Ni(II), Pd(II), and Pt(II) in a 0.2 M solution of hydrochloric acid was evaluated for the products obtained. Russian Journal of Applied Chemistry Springer Journals
