Optimization of Microcystin Extraction for Their Subsequent Analysis by HPLC-MS/MS Method in Urban Lake Water
Qu Jiang-qi, Zhang Qing-jing, Jia Cheng-xia, Liu Pan, and Yang Mu
Abstract—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.
