The nitrify lignite is prepared from Longkou lignite with nitric acid,so that the effective adsorption of humic acid is increased.A test for the adsorption of chromium-ion with the nitrify lignite has been carried out.The capacities of lignite,adsorption kinetics,adsorption models and the effect of pH were studied.The results indicated that the nitrify lignite had good adsorption properties to chromium-ion and the adsorption isotherms were consistant with Langmuir equation.
