A continious flow method for measurement of organic substances (OS) in water has been developed on the chemiluminescent (CL) reaction between organic subustances and hydorgen peroxide in the presence of formaldehyde in alkaline solution. This CL method was characterized the CL intensity of polynucleated compounds were greater compared with saturated straightchain compounds (saturayed alcohol, acetic acid). The limit of detection for humic acid (HA) was 50 ppb (w/w) and the relative standard deviation for six measurements of 1.0 ppm (w/w) of HA was 1.6%. Cations such as Na+, K+, Mg2+ and Fe3+ and anions such as PO43-, NO3-, CO32-, SO42-, Cl- and Y- (NaEDTA) did not interfere with the detemination of HA. Addition of Mn (II) enhanced the CL intensity. Three results measured by CL, CODCr, TOC methods for natural water samples were in good agreement. The correlation coefficient of CL intensity to TOC and CODCr were 0.85 and 0.81, respectively.
