A comparative study of the kinetics and isotherm of adsorption of a cationic dye by different natural wastes

In many countries, water pollution from industrial wastewater is a serious problem. This type of pollution can have a harmful impact on the environment, to reduce the effects of these pollutants, several physico-chemical methods are implemented, in particular adsorption on bioadsorbents, it is a com...
