SPE, Solid Phase Extraction; MIP-1, molecularly imprinted polymer formulated with MAA and EGDMA; MIP-2, molecularly imprinted polymer formulated with APMSA and EGDMA and MIP-3, molecularly imprinted polymer formulated with IA and EGDMA.
MC-LR, microcystin-LR; APMSA, 2-Acrylamido-2-methyl-1-propanesulfonic acid; MAA, methacrylic acid; IA, itaconic acid; EGDMA, ethylene glycol dimethacrylate; ACN, acetinitrile.
S, BET surface area; Vp, specific pore volume; and dp, average pore diameter were calculated from nitrogen absorption measurements.
