Abstract

Abstract Nitrilotriacetic acid was separated (as its tri- n-butyl ester) from twenty-four other fatty, phenolic and polycarboxylic acids, using prepacked commercial OV-210 columns. Quantitative analysis down to 0.010 mg nitrilotriacetic acid per liter was demonstrated. The molar responses and retention times of the acids, relative to phthalic acid, were determined.
