Obtaining a composite with riboflavin based on a natural sorbent
Abstract
Glauconite is a widespread mineral of sedimentary origin in nature. Glauconites from different deposits have different chemical compositions and different sorption and ion-exchange capacities. The characteristics of glauconite from the Beloozerskoye deposit in the Saratov region have been little studied, although it is one of the most promising. Riboflavin (vitamin B2) is one of the most important water-soluble vitamins, a coenzyme of many biochemical processes that play a significant role in maintaining human health. Composites based on glauconite and riboflavin can become a promising sorbent in animal husbandry. The aim of this work is to study the sorption characteristics of the enriched fraction of glauconite from the Beloozerskoye deposit in the Saratov region in relation to riboflavin and to obtain a biologically active composite based on it. The main sorption characteristics of glauconite in relation to riboflavin were determined spectrophotometrically. The surface morphology of glauconite grains was studied using scanning electron microscopy. A scaly structure of the sorbent under study was revealed, which significantly increases its sorption capacity. The enriched fraction of glauconite from the Beloozerskoye deposit in the Saratov region was used as a sorbent. The phase composition of the studied glauconite is represented by glauconite, montmorillonite, quartz and feldspars. Using the magnetic separation method, an 85% glauconite concentrate was obtained from the initial glauconite ore with a content of 40%. The optimal pH of riboflavin sorption on glauconite was selected, the degree of extraction was calculated (R=91.2±1.9%), the sorption time and mass of the sorbent were selected. A sorption isotherm was constructed, which is approximated by the Langmuir equation. The monomolecular nature of adsorption on the glauconite surface with the participation of active centers of both acidic and basic nature was revealed. The Langmuir constant (KL=1.04 l/mg) and the maximum sorption capacity (SC=1.03 mg/g) were calculated. The possibility of sorption of riboflavin by glauconite was established. The creation of composites with biologically active substances is a promising area of research and is in demand as enterosorbents in veterinary science, medicine and agriculture.
