In this study we developed the analytical methods for the determination of anatoxin-a, one of neurotoxin using HPLC/FLD system and this analytical methods were applied to real sample. For the HPLC/FLD analysis of anatoxin-a samples were concentrated on WCX(Weak Cation Exchanger) SPE and then anatoxin-a in concentrate was derivatized with NBD-F solution. Supernatant was injected on HPLC system. The LOD value for anatoxin-a in HPLC/FLD method was 24.3 ng. We determined the anatoxin-a content of lyophilized anabaena flos-aquae and 20 ㎍/g d.w. of anatoxin-a was detected. Although there are various water treatment processes for removing neurotoxins were suggested no process give simultaneous and complete removal of neurotoxins. It was cocluded that nanofiltration which reject material by size can be a process for removal of neurotoxins. |
