Abstract

The invention discloses magnetic polymerization ionic liquid for detecting microcystic toxins and a preparation method and an application of the magnetic polymerization ionic liquid. The magnetic polymerization ionic liquid is a granular particle which is formed by a carrier, functional monomer and cross-linking agents in a polymerization manner under the effect of initiating agents; the functional monomer is 1-vinyl-3-ethylimidazole hexafluorophosphate; and the cross-linking agents are 1, 4-butane-3, 3'-bis-1- ethylimidazole hexafluorophosphate. The magnetic polymerization ionic liquid which is prepared in the polymerization manner by using the 1-vinyl-3-ethylimidazole hexafluorophosphate as the functional monomer and using the 1, 4-butane-3, 3'-bis-1- ethylimidazole hexafluorophosphate as the cross-linking agents can quickly reach an adsorption equilibrium state on MC-RR and MC-LR, and has high adsorption capacity and high selective adsorption capability, and the maximum adsorbing capacities of the MC-RR and the MC-LR are 10.32 micro mol/g and 10.88 micro mol/g respectively.

Description

technical field [0001] The invention relates to a magnetic polymer, in particular to a magnetic polymer ionic liquid used for detecting microcystin and its preparation method and application. Background technique [0002] Microcystin (MC), a hepatotoxin produced by cyanobacterial blooms, is a strong liver tumor promoter. At present, more than 70 isomers of MC have been found, which are relatively common, among which MC-LR is the most toxic. With the eutrophication of water bodies, the harm of cyanobacteria blooms and red tides to the water environment has become one of the major environmental safety issues that our country pays attention to. [0003] Microcystins are secondary metabolites produced by cyanobacterial blooms. At present, in China's drinking water hygiene standard (GB 5749-2006), the microcystin content is limited to 1 μg / L, which puts forward higher requirements for the quality of drinking water source water. There are three main hazards of microcystins: 1) ...
