| Abstract: | Carboxymethylchitin is adopted to treat Alizarin Yellow GG.A study is devoted to the effects of pH,amount of addition carboxymethylchitin,temperature and time on the decoloration of the solution.Result shows a good flocculent decolorizing effect of carboxymethylchitin on Alizarin Yellow GG.When the amount of addition carboxymethylchitin is 0.0858g/L ,the adsorption time is 5h at 25°C,pH is 3,decoloration is very good, with rate of decolorization up to 85.96% and removal rate of COD 73.91%. |
