Physical and chemical characteristics of the composite material Zeolite-Alginate-Fe(OH)3

Abstract

Abstract The article examines the physical and chemical properties of Zeolite-Alginate-Fe(OH)3 granules, which were synthesized by applying iron hydroxide to alginate-zeolite granules. In the work, the process of synthesis and granulation of Alginate-Zeolite-Fe(OH)3 adsorbent was investigated. The process of application of the active magnetic phase of the adsorbent was studied. The dependence of the static strength of the granules on the content of the solid phase (43 - 51 kPa) was established. Adsorption of lead cations from aqueous solutions was investigated. For the Zeolite-Alginate-Fe(OH)3 adsorbent, the specific adsorption capacity was 13.195 mg/g. It was established that the addition of trilon B in the synthesis process leads to an increase in adsorption capacity by 40%.
