The adsorption potential of the Perlin clay for the removal of lead ions from aqueous solutions was tested. The adsorption amount measured at the different temperature (25°C, 45°C and 65°C) and Ph (2, 3 and 5). A high adsorption capacity aws calculated. An increase in the retention capacity with increasing temperature was measured. The influence of pH in the acidic range was investigated. The measured increase in the adsorption rate at higher pH values (5) was explained through the influence of H+ ions on the complex ion formation.
