METHOD FOR PRODUCING A sorbent based on polystyrene TO REMOVE boron compounds from aqueous solutions

摘要

A process for preparing a sorbent based on polystyrene for extraction of boron from aqueous solutions, characterized in that the feedstock using linear polystyrene, which in the first stage is treated with fuming nitric acid in the second step from the obtained polinitrostirola reacting it with a water-alcohol solution of tin chloride ( II) synthesized poliaminostirol that the third step is reacted with glycidol in a molar ratio poliaminostirol: glycidol = 1: (1-4) under the influence of ultrasound, ekstragi ruyut product obtained hot water-soluble alcohol or ketone and air dried.
