Application of Modifie d Sulfur Nanoparticles as a New Sorbent for Solid Phase Extraction a nd Determ ination of Linuron

Solidp hase extraction (SPE) is a routine extraction method for the pretrea tment of sa mples with complex matrices such a s seawater, because it o ffers the advantages of enrichment, high recov ery, simplicity and high speed [۱]. Recently, th e use of nanoparticles (NPs) for s ample extraction in SPE has garnered research interest. Compared with the micrometer -sized particles used for SPE, NPs offer a sign ificantly higher surfac e area-to-volume ratio and a short diffusion ro te, resulting in high extraction capacity, rapid e xtraction dy namics, and high extraction efficie ncies [۲]. Nanosized su lfur particl es are one class of NPs that have been widel y applied in pharmaceuticals, synthesis of nanocomposites for lithium batteries, synthesis of sulfur nano wires with c arbon to form hybrid materials with useful properties for gas sensor. In agricultural field, sulfur is use d as a fungi cide against the apple s cab disease under colder conditions, in conventional culture of grapes, and several other crops [ ۳].
