An analysis of the data published in the last decade on the use of magnetic nanoparticles (MNPs) modified with inorganic, organic, and polymeric substances for the sorption and preconcentration of anionic azo compounds used as indicators, organic reagents, food and textile dyes in water media and also in food and environmental samples is presented. The main focus is on the revelation of the effect of the modifier nature and sorption conditions (pH; dye concentration; MNP weight, specific surface area, pore diameter, and volume; zeta potential; and magnetization value) on the recovery, sorption and desorption time, and also on the sorption capacity of the MNPs with respect to various acidic mono- and bisazo dyes. The main trends in the development of methods of magnetic solid-phase extraction are noted.
