Study on the adsorption of crystal violet on red mud modified by sodium dodecylbenzene sulfonate (SDBS)

In this paper, different modifiers were used to modify red mud and adsorb crystal violet. The results showed that the red mud modified by sodium dodecylbenzene sulfonate had a better adsorption effect on crystal violet. The effects of adsorption time, pH value, initial concentration of crystal viole...

Description
Summary:In this paper, different modifiers were used to modify red mud and adsorb crystal violet. The results showed that the red mud modified by sodium dodecylbenzene sulfonate had a better adsorption effect on crystal violet. The effects of adsorption time, pH value, initial concentration of crystal violet and salt ion on the adsorption of crystal violet on modified red mud were studied, respectively. 120 min was selected as the adsorption shock time. The results showed that the basic condition was more favourable to crystal violet adsorption, and the addition of salt ions was not conducive to crystal violet adsorption.
