Sorption of copper ions with natural clinoptilolite under the action of ultrasound in the isothermal mode

The sorption of copper ions from a solution of copper (II) sulfate by the native form of natural clinoptilolite under mechanical stirring and under the action of ultrasonic radiation of different power and under different modes of process implementation (continuous and cyclic) was investigated. Based on the obtained results, it was concluded that ultrasonic vibrations significantly intensify the diffusion processes in the studied system. Carrying out the process in the cyclic mode “US treatment – exposure without US” makes it possible to achieve a greater sorption capacity of clinoptilolite due to its more complete degassing.
