Using mesoporous molecular sieve MCM-41 as adsorbent, adsorption behavior that Cr(Ⅵ) in the water at the difference of temperatures, mass of adsorbent, adsorption time and initial concentration of chromium ion Cr(Ⅵ)was investigated, Experimental results show that the optimal adsorption conditions for removal chromium are at the temperature of 35 ℃, the initial concentration of 10 mg · L-1, adding adsorbent dosage of 0.1 g, adsorption time of 3 hours.Drawing the chromium ion adsorption isotherm at the room temperature 25 ℃ and then the adsorption isotherms was fitted for Langmuir and Freundlich-linear fitting, and the results are as follows.
