Abstract
Способ получения сорбента на основе полистирола для извлечения бора из водных растворов, отличающийся тем, что в качестве исходного сырья используют линейный полистирол, который на первой стадии обрабатывают дымящей азотной кислотой, на второй стадии из полученного полинитростирола взаимодействием его с водно-спиртовым раствором хлорида олова(II) синтезируют полиаминостирол, который на третьей стадии подвергают взаимодействию с глицидолом при мольном соотношении полиаминостирол : глицидол = 1:(1-4) под воздействием ультразвука, экстрагируют полученный продукт горячими водорастворимыми спиртами или кетонами и сушат на воздухе.A method for producing a polystyrene-based sorbent for extracting boron from aqueous solutions, characterized in that linear polystyrene is used as a feedstock, which is treated with fuming nitric acid in the first stage, and in the second stage from polynitrostyrene obtained by its interaction with an aqueous-alcoholic solution of tin chloride ( II) synthesize polyaminostyrene, which in the third stage is subjected to interaction with glycidol at a molar ratio of polyaminostyrene: glycidol = 1: (1-4) under the influence of ultrasound, extracts The resulting product is rinsed with hot water-soluble alcohols or ketones and dried in air.
