- Abstract
The removaI effect of sunset yellow by the activated carbon prepared by modified straw was studied, and the effectr of adsorption temperature, adsorption time, adsorption capacity, solution salinity and solution pH on the removaa effect of sunset yellow were analyzed. After being soaked in acid and alkali, the stalks and leaveo of the straw were carbonized and modified at 200 - 700 P. The results show that the adsorption effect of the leaveo soaked in alkaii was the best when the carbonization temperature was 700 P. As the adsorption temperature was 30 - 40 P, the adsorption effect of sunset yellow was the best. With the increase of adsorption time, the removal rate of sunset yellow first increased, llien decreased, and finally rose agaim The first critical point was about 30 min. When the dosaae of activated carbon was 0. 7 g, the adsorption effect of 50 ml of sunset yellow solution was the best. The optional solution salinity was 60%. pH had a small effect on the adsorption of sunset yellow, showing a fluctuating trend.
