Abstract:

Solutions of twelve typical dyes belonging to six categories were coagulated by four inorganic coagulants. On the basis of experimental results, the correlation between the rate of decolorization and the molecular structure of dye, the characteristics of coagulants were presented. At the same time, some mechanism of coagulation was also discussed.
