EXTRACTION-PHOTOMETRIC METHOD FOR DETERMINING CONTENT OF DINITROPHENYL

摘要

The proposed extraction-photometric method for determining content of dinitrophenyl consists in providing the reaction for producing the ion associate of dinitrophenyl with organic base, extracting the reaction product by organic solvent, and carrying out the photometric analysis of the extract. As the organic base, polymethine astrasole violet dye 3R is used. As the organic solvent, mix of toluene and chloroform with the component content ratio of 3:2 is used.
