The enzyme - linked immunosorbent assay ( elisa ) and high performance liquid chro - matography ( hplc ) analysis for detection of mc were optimized. the removal rates of mc by conventional water treatment processes were investigated through the laboratory study and the detection of mc in every process in meiyuan drinking water treatment plant. results showed that the prechlorination of eutrophic water led to the release of intracellular toxins to water phase
本文完善了mc的elisa和hplc分析方法，通過模擬試驗及水廠實測調查了富營養化太湖水中mc在常規凈水工藝中的去除特性，結果表明預氯化使藻細胞內的mc釋放出來，混凝沉澱對細胞外mc無去除作用，
砂濾可去除17 . 2 40 . 4的細胞外mc和19 . 0 36 . 6的總mc ，加氯消毒對細胞外mc和總mc的去除率分別為30 45 . 3和30 51 . 7 。
