Abstract
A new reagent system using p-aminoacetophenone for determination of trichlo rocetic acid (TCA) is described. The method involves modification of Fujiwa ra reaction, i.e. discharging the colour obtained by adding pyridine and al kali, with acetic acid followed by the addition of p-aminoacetophenone. The purple-red coloured dye formed has an lambda(max) at 520 nm. The method ha s been satisfactorily applied for the determination of trichloroacetic acid in air and a variety of environmental and biological samples.
