Abstract

The method of obtaining a chemical adsorbent of ammonia and hydrogen sulfide is proposed to be modified to improve sorption characteristics. The dependence of the kinetics of the process was studied - crystallization of solutions of copper (II) sulfate with a concentration of 2.19 mol/dm3 and 2.38 mol/dm3 depending on the method of preparation of the impregnating solution: thermal with heating to a temperature of 80 - 90 °C, using ultrasonic oscillations with a frequency of 22 kHz and an intensity of 3.5 W/cm2, and the dependence of the studied thermal method with the additional introduction of 0.01% surfactants into the solution with nonionic, anionic and cationogenic properties. Crystallization of copper sulfate was performed using a probe video microscopy system. The formation of smaller crystals is observed upon cooling of the solutions subjected to ultrasound. The introduction of surfactants did not affect the size of the crystals of copper (II) sulfate. The dependence of the physicochemical properties of a solution of copper (II) sulfate at a concentration of 1.17 mol/dm3 and 2.26 mol/dm3 on the introduction of 0.01% surfactant and a change in the temperature of the solution was studied. It was found that the introduction of a surfactant can effectively reduce the surface tension of the solution at a temperature of 80 °C and reduce the contact angle of the solution of activated carbon granules. Impregnating solutions of copper (II) sulfate are prepared using the above methods and samples of a chemical adsorbent of ammonia and hydrogen sulfide are made by impregnating granular activated carbon with the obtained solutions. It is proved that the use of surfactants and ultrasonic vibrations during the preparation of an impregnating solution allows to increase the amount of active form of copper on the surface of the carrier during impregnation, which helps to increase the dynamic capacity of chemisorbents.
