A simple method of analysis iminoctadine triacetate analysis in waste water from golf courses was developed. To achieve satisfactory identification and determination by LC/ESI-MSanalysis, four kinds of analytical columns including both reverse phase and normal phase were examined. Among these, the reverse phase columns having long chain alkyl groups (DivelosileC30 UG-3) gave a satisfactory separation of iminoctadine triacetate on the chromatography. The condition using ODS colum in combination with a mobile phase containing ion pair reagent gave the most excellent separation, but had the disadvantage of instability in the retention time of iminoctadine triacetate. The analytical condition using normal phase column was inappropriate because it gave a broad peak of iminoctadine triacetate with high tailing factor. In the pretreatment process, WCX short column was chosen to extract iminoctadine triacetate from waste waters, which does not need to add HCl in the eluate solution as other short column (e.g. CBA column) does. By the method using WCX column in the pretreatment process as well as Divelosile C30UG-3 column in LC/ESI-MS analysls, the recovery percentage of spiked iminoctadine triacetate in waste waters( 0.01mg.l-1) was determined to be 93% in average. The quantification limit of iminoctadine triacetate was 0.0004mg.l-1 in water samples.
