Review on functionalized magnetic nanoparticles for the pretreatment of organophosphorus pesticides

Abstract Organophosphorus pesticides are currently extensively applied on the control of agricultural and forestry pests. The number poisonings deaths caused by organophosphorus increasing year year. Because complex matrix, numerous interfering substances, low poison content, pretreatment methods crucial for detection analysis such cases. As an adsorbent used pretreatment, magnetic nanoparticles have advantages simple preparation, convenient modification, superparamagnetism, hydrophilicity. Microextraction can be performed with small amount in a short time, target substances separated external field. In this paper, latest research achievements reviewed. Based introduced characteristics preparation nanoparticles, paper outlines applications different functionalized predict potential prospects.
