NOVELTY - Preparing arsenic fluorine resin involves adding titanium dioxide particles (10-20 pts. wt.) to water (150-200 pts. wt.) and then stirring mixture to obtain suspension of titanium dioxide. The mixture is prepared by dissolving graphene oxide (20-40 pts. wt.), acetic acid (5-8 pts. wt.), chitosan (15-20 pts.wt.) to water (100-150 pts. wt.). The obtained mixture is added dropwise to suspension of titanium dioxide to obtain mixed particulate suspension. Initial reaction mixture is obtained by adding polyvinyl (10-30 pts. wt.) and sodium chloride (4-7 pts. wt.) to mixed particulate suspension. USE - Method for preparing arsenic fluorine resin used for purifying groundwater (claimed). DETAILED DESCRIPTION - Preparing arsenic fluorine resin involves adding titanium dioxide particles (10-20 pts. wt.) to water (150-200 pts. wt.) and then stirring mixture to obtain suspension of titanium dioxide. The mixture is prepared by dissolving graphene oxide (20-40 pts. wt.), acetic acid (5-8 pts. wt.), chitosan (15-20 pts.wt.) to water (100-150 pts. wt.). The obtained mixture is added dropwise to suspension of titanium dioxide to obtain mixed particulate suspension. Initial reaction mixture is obtained by adding polyvinyl (10-30 pts. wt.) and sodium chloride (4-7 pts. wt.) to mixed particulate suspension. The organic phase solution is obtained by mixing divinylbenzene (30-50 pts. wt.), divinyltoluene (10-20 pts. wt.), isopropyl acetate (20-40 pts. wt.), methyl methacrylate (20-40 pts. wt.), vinylpyrrolidone (10-20 pts. wt.) and porogen (40-80 pts. wt.). The organic phase solution is mixed with initial reaction mixture. Glutaraldehyde (20-40 pts. wt.) and tert.-butyl ester (5-10 pts. wt.) are added to the obtained solution. The solution is then heated, filtered, washed and dried in vacuum to obtain adsorbent.
