Embodiment Construction
[0032] Below in conjunction with specific embodiment, further illustrate the present invention.
[0033] The detection method of microcystin MC-LR in water body, including:
[0034] (1) Sampling: during the outbreak period of Microcystis aeruginosa, 1L water samples were taken with a sampler at a monitoring point of Wuxi Taihu Lake at a depth of 20-30cm, and the number of samples was 31. Nine samples were randomly selected as samples to be inverted, and other samples were used to construct the inversion equation.
[0035] (2) With reference to the national standard GB / T20466-2006 method, the Agilent 1200 liquid chromatograph was used to determine the content of microcystin MC-LR in the water sample, which was used for the establishment of the inversion equation and inversion detection;
[0036] (3) Extract the extracellular organic matter of Microcystis aeruginosa in the water sample: the extracellular organic matter of Microcystis aeruginosa is divided into two parts: dEOM (...
