Abstract:
A fluorometric procedure for the determination of o-phthalic acid by conversion to fluoresceln is described. The optimum amount of o-phthalic acid for application of the method is 50–5000 μg. The determination can be carried out with a relative error of less than 5% even when significant quantities of common o-phthalic acid contaminants are present.
