Abstract

Graphical abstract This paper describes the development of a new design of hollow fiber solid/liquid phase microextraction (HF-SLPME) for determination of brilliant green (BG) residues in water fish ponds. Simple scheme of pseudo-stir bar HF-SLPME device. (a) Magnetic stoppers (iron pins; 1.5 mm × 0.6 mm); (b) Accurel Q3/2 polypropylene hollow fiber membrane (1 cm length, 600 μm I.D., 200 μm wall thickness, and 0.2 μm pore size); (c) MWCNTs reinforced 1-octanol.
