Examination of metallochromic indicators and water-soluble reagents for metals by planar electrophoresis

Analyst, The, 1986
Water-soluble azo, phthalein, sulphonphthalein and anthraquinone indicators and reagents were subjected to low-voltage electrophoresis on cellulose acetate sheets at pH 2–12. All dyes except low-sulphonated azo dyes yielded one or more sharp bands showing good mobility and resolution over some range of pH values.
