Abstract
In the present investigation, the effect cif contact time on the per cent removal of Icad(II) ions at the solution pH, 3.85, and at the temperature, 35.0°C, using the lignite particles of size 0-63 mic and weight 200 mg was determined. Lagergren equation was tested. Lagergren K values were determined at different temperatures.
