Abstract: | A novel titrimetric method for determination of aminobenzoic acids is based on their reaction with excess of bromine to form N-bromo-2,4,6-tribromoaniline, which liberates an equivalent amount of iodine when treated with iodide. The method is applicable to the aminobenzoic acids in the range 0.1-5.0 mg, with a recovery ranging from 96 to 99.7% and a coefficient of variation of 0.2-2.0%, depending on the concentration level. |
