This work evaluates different magnetic sorbents such as Fe₃O₄@MIL-101(Cr), Fe₃O₄@MIL-101(Cr)@NH₂, and Fe₃O₄@MIL-101(Cr)@SO₃H for magnetic solid phase extraction (MSPE) and further selected Fe₃O₄@MIL-101(Cr)@NH₂ to determine paraben content in chili powder and facial toner samples. Fe₃O₄@MIL-101(Cr)@NH₂ is an efficient sorbent material specially designed for MSPE, which profoundly extracted nine parabens within a short span of just 6 min, driven by π–π interaction and hydrogen bonding. And a detailed optimization and LC–MS/MS analysis was carried out. Fe₃O₄@MIL-101(Cr)@NH₂ exhibited superior extraction efficiency, enabling subsequent quantification via LC–MS/MS. The limit of detection ranged from 0.063 to 0.622 ng mL⁻¹ and limit of quantification of 0.211 to 2.073 ng mL⁻¹ were a good recovery in the range of 76.2%–108%.

Therefore, perovskite oxides mixed with metal elements become ideal samples for studying the surface and catalytic performance of catalysts. In this review, various metal perovskites are clearly classified and introduced according to the corresponding synthesis methods, including hydrothermal method, sol–gel method, and high-temperature solid phase, as well as coprecipitation. The excellent properties of perovskite make it extensively used in nanotechnology, chemistry, environmental protection, and material science, especially in solar cells and sensors. In particular, the nanosized perovskite materials are becoming more and more popular in sensors, which was reviewed in detail here.
