dc.description.abstract	Cadmium (Cd) and arsenic (As) adsorption and desorption by goethite and clinoptilolite were the subjects of this article. Experimental variables were the concentrations of Cd, As, background electrolyte, and the solution pH. Cadmium adsorption by goethite and clinoptilolite increases with the increase of pH and with the decrease of electrolyte concentration. Maximum Cd desorption by goethite was found at pH6.0 and by clinoptilolite at pH8.0 and 0.1M potassium chloride (KCl). Maximum As desorption by goethite was found at pH8.0 and by clinoptilolite at pH10.0 and 0.01M KCl. The experimental results of Cd adsorption were successfully fitted to Langmuir, Freundlich, and Temkin isotherms, and the experimental results of As adsorption were comparable successfully fitted to Freundlich and Temkin isotherms.	en
