Method for purifying various cyanobacteria toxins from algae bloom water body

The invention discloses a method for purifying various cyanobacteria toxins from an algae bloom water body, and aims to overcome the defects that in the prior art, cyanobacteria toxin standard substances are high in price, lack of mixed standard substances and few in purchase channels, and monitoring and detection of the cyanobacteria toxins are affected. B, enrichment and concentration of cyanobacteria toxin: carrying out enrichment and concentration through a solid-phase extraction column combining an HLB plus small column with a PGC column, and enabling a cyanobacteria toxin extracting solution to pass through the HLB plus small column and then pass through the PGC column; c, eluting cyanobacteria toxin: adjusting the sequence of the solid-phase extraction columns, and enabling the eluent to pass through a PGC column and then pass through an HLB Plus small column; and D, blow-drying the eluent containing the cyanobacteria toxin to obtain cyanobacteria toxin dry powder. According to the types and characteri
