- 中文摘要: Separation of the herbicides 2,4-D methyl ester and pentachlorophenol from aqueous solutions by paper capillary permeation adsorption method was studied using paper. Nearly 43% and 99% of the investigated herbicides 2,4-D methyl ester and pentachlorophenol, respectively, could be separated under optimum conditions. The effect of pH on the separation efficiency was studied in particular. At pH1-11 and 1, the maximum separation was achieved for 2,4-D methyl ester and pentachlorophenol, respectively. The effects of herbicide concentration and some salts on the separatability were examined. Desorption techniques by elution with water to remove the herbicides from paper were developed. Moreover, the selective separation of the herbicides from the dispersion dyes methylene blue and congo red was attempted.
