The paper electrophoretic method to separate and identify eight preservatives (salicylic acid, benzoic acid, sorbic acid, dehydroacetic acid, ethyl p-hydroxybenzoate, resorcinol, β-naphthol and p-chlorobenzoic acid), a sterilizer (nitrofurazone), and three artificial sweetners (saccharin sodium, sodium cyclamate and dulcin) was investigated by using 1% borax solution, Kolthoff buffer solution (pH 4.0 and 5.8) or Atkins-Pantin buffer solution (pH 10) as the electrolyte. The mobilities of the compounds were shown as the relative one to flavianic acid, and tabulated. All the compounds could be identified by selecting the electrolytes.
