The invention relates to methods for the preparation of sorbents and can be made in 1ls. The company is engaged in the production of human and environmental protection products from ammonia and amines. : According to the main bus. 858910 a method of obtaining a sorbent for the extraction of and: amine is known. | Conclusion in the treatment of cation exchanger with transition metal salts, such as copper, and washing with water with subsequent treatment with an alkali solution. Disadvantages: The above mentioned method is: low capacity and short time of the sorbent layer; The purpose of the invention is pseudo-absorbing ability and an increase in the time of physical action,; The goal is achieved by the 4Td according to the method of obtaining: a sorbent for extracting ammonia and lmines, the cation exchanger is converted into a copper form and is processed with a solution of an alkali, and then further treated with an aqueous solution of a cobalt salt or nickel, washed with water and treated with acid vapor. ; : As cation nitrate, fibrous sulfocatirnite based on Cg sulfoporistyrene is used. When treated with an alkali of a cation exchanger in a copper form, copper ions are displaced with alkali metal ions with the formation of copper and hydroxide, which is evenly distributed in the mass of the cation resin A. GiDrok1 yedi Insoluble in water and therefore not washed out during subsequent processing of water. the cobalt or nickel salt, the ions of which displace alkaline metal eln. Since the copper hydroxide on the air is converted into oxide, copper, slightly binding ammonia, it is converted into a water-soluble salt by treatment with Acid Vapors. As a result of thisThe copper phosphate forms cation exchanger in the form of cobalt or: nickel filled with an iodine-soluble copper salt. Copper, cobalt (or nickel) ions are able to bind ammonia, form complex compounds with it. Since metal nons are distributed evenly throughout the mass of cat.itonite then, to improve the absorption kinetics of the fiber, are fibrous cations, having a much louder fiber diameter than the size of the IT: granular sorbent. Example 1. Take a sulfonic polystyrene based on sulfopolystyrene in copper: the form (exchange capacitor 3-3.5 mEq / g, fiber thickness 5-10 μm), treated with a 5.% aqueous KOH solution / washed with water until neutral, and then treated with 5% water: Cobalt chloride solution, washed with water and dried to air-dry. After this fiber sorbent is treated with gaseous hydrogen chloride. The result is a cation exchange resin in the form of cobalt, containing 17% weight. hlorida.medi, which corresponds to obkunnoy capacity of the original cation exchanger,. . .:,; A portion of the sorbent with a height of 3 to 10 mm is placed in a dynamic column with a diameter of 4.5. Air is passed in. Containing 0.3 mg / l of ammonia at a speed of 5 cm / s with a relative humidity of 90% and 23–25 C. on: leaving the column, determine the protective effect of the sorbent layer until ammonia breakthrough. The amount of ammonia bound is determined by chemical analysis of the sorbent samples. And measure 2. As in Example 1, only a 5% aqueous solution of nickel sulphate is used for the treatment of the sorbent instead of coxter chloride. The content of copper chloride in the sorbent is 3-3.5 mg-eq.v / g. P. Im 3, In order to obtain comparative data on the efficiency of air purification from ammonia, the absorption capacity and the time of the protective action of the sorbent obtained by a known method are determined. And this carboxyl cation exchanger of the KRK brand is converted into the H-form in the standard way, and 5 g of the cation exchanger are placed in a beaker, washed with a 1.0 n solution of copper sulfate with a volume of 100 ml. Then, the catonite saturated with copper ions is washed with water and treated with 0.2 N sodium hydroxide solution until the pH of the alkaline solution ceases to change. The finished sorbent is washed with water, dried to air without air and tested as in Example 1.. Comparative data of the absorptivity and time of the protective effect of sorbents obtained on the proposed and known methods are shown in the table.
