A review: Recent advances in solid phase microextraction of toxic pollutants using nanotechnology scenario

The enrichments of emergent pollutants from different compounds with complex matrix makes it critical and stimulating to develop new solid phase microextraction coatings tools with high enrichment capacities provide excellent chances for it. This review precises the used nanomaterials for the fabrication of solid phase microextraction coatings, including metal oxide nanoparticles, metal nanoparticles, carbon-based nanomaterials, and silica nanoparticles. To obtain solid phase microextraction coatings with outstanding physical performance, high enrichment capacity, anti-interference ability, and suitable fiber coating technique and supports are designated according to the assets of coating materials. In addition, the analytes influencing the enhancement effect and the factors of coating materials are summarized and explained preliminarily, promoting for the further design of cutting-edge coating materials with boosted the performance.
