Abstract:
An efficient and fast dispersive magnetic solid phase extraction method was developed using MIL-101(Cr)/poly (mercaptobenzothiazole)@magnetite nanoparticles for the preconcentration and determination of nitrophenols in river and rain water samples. High-performance liquid chromatography-Ultraviolet instrument was applied for the analysis of target nitrophenols. The effect of several variables on the extraction performance was explored via design of experiment approach. Limits of detection and linear dynamic ranges were attained in the range of 0.05-0.10 µg/L and 0.2-250 µg/L, respectively. The enrichment factors were in the range of 317-363. The precision (n = 3) of dispersive magnetic solid phase extraction method was in the range of 5.3-6.8%. Eventually, the method was utilized for the analysis of target nitrophenols in river and rain water samples.
