ABSTRACT:OBJECTIVE To establish a method for determination of triclosan in cleaning solutions. METHODS Triclosan was directly determined with the first-order derivative UV spectrophotometry to diminish the disturbance of other ingredients in cleaning solutions. RESULTS The first-derivative spectrophotometry showed good accuracy and repetition. The average recoveries at high, medium and low concentrations were %, % and %, respectively, with RSD %, % and % (n=3). CONCLUSION This method can be used in the analysis of some cleaning solutions containing both triclosan and some other fragrant without separation process. The interference of fragrant in the preparation was eliminated.
