| Abstract: | In order to get optimum conditions,single-factor response surface optimization method was used in the pre-treatment process of enriching,leaching and eluting low concentration of microcystins(MC-RR and MC-LR)in water.The results showed that it could get the best leaching effect with 25%methanol solution,the best recoveries of MC-RR and MC-LR were 89.4%and 90.7%by using 75%methanol solution as eluent which optimized by One Factor design.The method had good linearity in the range of 0.100 mg/L to 5.00 mg/L,the detection limits of MC-RR and MC-LR were 0.07μg/L and 0.04μg/L,the recoveries of actual water samples were between 80.6%and 84.9%,and the RSDs of duplicate detection were 1.6%and 2.4%,respectively. |
