| Abstract: | Trace Microcystin（MC-LR） in drinking source surface water was determined by HPLC-ESI-MS with solid phase extraction and test conditions of chromatography and mass was optimized.The results showed that mobile solution [V（methanol）∶V（water）=60∶40] which contained 0.1% methanoic acid,selective quantity ion（m/z=996.3）.Good linearity of the method was obtained in range from 0.100 mg/L to 2.00 mg/L,the detection limits 0.02 μg/L,spiked standard recoveries of blank samples（96.2±5.4）%. |
