英文摘要 | Separation of the dyes methyl violet, methylene blue, and congo red from aqueous solutions by paper capillary permeation adsorption method was studied using paper. Nearly 100% of the investigated dyes could be separated under the optimum conditions. the effect of pH on the separation efficiency was studied in particular. At pH 5-9, 1.3-11, and 7-11, the maximum separation was achieved for methyl violet, methylene blue and congo red, respectively. the effects of dye concetration and some foreign ions on the separatability were examined. Moreover, the selective separation of some dyes was attempted by elution with chemical reagents. |
