With sodium dodecyl sulfate modifier, a novel organic modified bentonite adsorbent was synthesized and applied to adsorb methylene blue. The results show that the removal ratio of methylene blue was over 96% under following conditions: the dosage of the adsorbent is 8g-L, the adsorption equilibrium time is 1.5h, the temperature is 25℃, and the pH value is 9.
