    This invention relates to the field of polymer adsorbents,; used to remove anionic from aqueous solutions, especially from wastewater, for example, filtrates, residual baths from bleaching processes, or dyeing from drains after rinsing and washing.
    The purpose of the invention is to obtain an adsorbent with a high adsorption capacity.

    pH = 4.6, adjusted using concentrated HCt, mixed with 26.4 g of N, N-dimethylolurea and heated to. The molar ratio of the starting materials was 1: 1.8. To this mixture was added 10 ml of 15% sulfamic acid, and the reaction mixture solidified. Then the mixture is heated for 1.5 hours under reflux, the reaction mixture is drunk on a drying sheet and further condensed in a vacuum oven at 8590 0. After 15 hours, 41.5 g of a light yellow vitreous product is obtained, which is crushed and absorbed 2000 ml. water. After 30 minutes of stirring at room temperature, filtration is performed through a filter cloth and the product is dried in a vacuum oven for 16 hours. 20.0 g of a slightly yellow powder with a nitrogen content of 25.3% is obtained,

To this mixture, 10 ml of 15% sulfamic acid is added, and a fine suspension is formed, transparent as a glass. The molar ratio of the starting materials is 1: 2.
    Then it is heated for 1.5 hours to 80-85 ° C, the reaction mixture is poured onto the drying sheet and further condensed in a vacuum drying cabinet at 85-90 ° C. After 15 hours, 1500 ml of water is obtained and absorbed. After 30 minutes of stirring at room temperature, filtration is performed through a filter cloth and the product is dried in a vacuum oven for 15 hours at 85-90 ° C.
