One of the world's biggest problems is the lack of drinking water. The most effective methods are sought for water treatment. The latest methods include sorption on the solid layer. In order to design the arrangement of the cleaning process, it is necessary to know the adsorption isotherm and the kinetic course of sorption. The article contains laboratory experiments designed to determine the sorption parameters of nickel cations sorption on natural zeolite - clinoptilolite, which is a low cost and environmentally friendly sorption material.
