| Abstract: | Abstract A simple, rapid and sensitive titrimetric method with amplification has been worked out for the determination of 50–2000μg of o-cresol, m-cresol or p-cresol. It is based on bromination of these compounds with bromine water to form the corresponding hypobromites, which liberate an equivalent amount of iodine when treated with iodide. The sensitivity of the method has been increased using the Leipert amplification procedure. The coefficient of variation does not exceed 1.5% for above 500μg of the cresol, but increases to 2.2% at the 50μg-level. |
