Abstract:

The alkaline white mud was dipped in dilute hydrochloric acid, and filtered to prepare the leaching solution. The removal effects of activated light yellow K-6G, acid orange Ⅱ and direct yellow R from an aqueous solution using the leaching solution of white mud were studied. The results showed that the leaching solution of white mud was particularly effective in removing activated light yellow K-6G, acid orange Ⅱ and direct yellow R. Particularly when the dosage was 2g／L, the pH respectively was 12.5, 12.0 and 12.0, the maximum removal efficiencies reached up to 93.5％, 97.5％ and 99.8％ respectively. The appropriate reaction time was 90 s. It also indicated that the adsorption behavior of the anionic dyes on the hydroxide precipitates formed in alkaline solution by leaching solution in alkaline solution fitted well with the Freundlich isotherms. The adsorption process was exothermic in nature.

Key words: leaching solution of white mud, adsorption, anionic dyes, decolorization
