摘要：This paper represents to propose an effective extraction procedure for traditional toxin determination techniques in urban lake.Efficiency of each extraction solvent as well as other key parameters affecting extraction efficiency including ultrasonication time and extraction pH were evaluated and optimized.The present study results indicated that 40% acidified methanol (pH~3) with sonication 15~20min has been shown to be a rapid and efficient method for the routine analysis of a wide range of microcystins in water samples.Our study also suggested that analytical method based on HPLC–MS/MS with SPE techniques provides a simplified enrichment procedure and rich information for both quantization and identification effective tool for analysis of urban landscape water quality.The development of this method may facilitate the understanding of the best extraction method for the routine analysis of microcystins in water bodies.Moreover, it may be valuable for purification scale.
