SIMULTANEOUS SPECTROPHOTOMETRIC DETERMINATION FOR PHENOL, PYROCATECHOL, RESORCINOL AND HYDROQUINONE BY RADIAL BASIS FUNCTION NEURAL NETWORK

Gong Chengyong, Sun Jingyue, Jin Jihong (College of Materials Science and Chemical Engineering, China University of Geoscience, Wuhan 430074, China)  
The four components system of phenol, pyrocatechol, resorcinol and hydroquinone was studied by spectrophotometry. Serious overlapping of the absorption peaks made it difficult to determine the four components simultaneously. The radial basis function network being used as the mathematical model, the content of the four components in water samples was determined with the recovery of 95.7%~109.2%.
