Abstract	우리나라 영산일 bentonite를 KF, NH4Cl등의 염과 혼합하여 200-500℃로 가열처리하여 수세 건조한 시료의 methylene blue 흡착능을 조사하였다. NH4Cl를 혼합하여 처리하였을 경우에는 methylene blue 흡착능이 다소 개선되었다. KF를 혼합하여 처리하였을 경우에는 200-300℃의 처리에서 methylene blue의 흡착능이 원시료의 약1.7배까지 개선되었다. FeSO4 나 Na2CO4등의 염과 혼합하여 처리하였을 경우에는 오히려 methylene blue 흡착능이 감소되었다. The adsorptivity of Methylene Blue on Korean Yeongil bentonite which was premixed with a salt of KF or NH4Cl etc., treated at 200-500℃, washed and dried, was studied. In case of treatment with NH4Cl, slight improvement of the adsorptivity of methylene blue on the products was observed. With KF, treated at 200-300℃, the best results was obtained. The adsorption capacity of the products was improved about 1.7 times than that of original bentonite. With FeSO4 or Na2CO3 etc. improvement of the adsorption capacity on the products was not observed.
