摘要: Electrospun polymer nanofibres were used as novel solid-phase extraction (SPE) sorbents to extract and quantify the microcystins (MCs) including microcystin-RR (MC-RR) microcystin-LR (MC-LR) from in-suit water samples. The parameters that influenced efficiency studied, amount of nanofibre, eluted solvent, volume, pH, sample volume. Under optimized conditions, a linear response for MC-RR MC-LR over range 0.25–4 µg/L was achieved with r2 values 0.998 0.997, respectively. recovery 97–102% 98–100%, respectively, when MC concentration 0.25–4 µg/L. When their concentrations ranged 0.05 0.25 µg/L, MCs could be detected high accuracy by nanofibre SPE sorbent combined nitrogen gas. Due its simplicity, environment-friendliness, efficiency, reusability, sensitivity, electrospun can applied de...
