The removal of lead from water by sunflower seed peel was investigated. It was found to depend on the solution pH, temperature, adsorbent dose and initial concentration. The maximum adsorption efficiency observed was 99% at the equilibrium state. The most successful adsorption was performed at pH 6, 60 degreesC and initial concentration of 30 ppm. It was also found that the temperature changes have no big effect on the adsorption capacity.
