“…Centrifuged 5 min at 10179g. UA–MSPD using an ultrasonic bath was the most effective treatment [116] 17 pyrethroids and chlorpyrifos Foodstuff (beef, chicken, eggs, fish, and milk) UAE-SPE ES: hexane/dichloromethane (2: 1) 0.1 g sample (10 % fat) and 0.3 g (less than 10 % fat). Sonication twice with 20 mL of ES for 15 min at room temperature.…”

“…Applying the same ultrasound-assisted extraction procedure, they were able to analyze the matrix effect of these complex samples and to obtain a useful method for sulfonamide trace analysis employing a reduced amount of solvents and a short analysis time. On the other hand, researchers from Universidade Federal do Rio Grande (Brazil) determined organophosphates, carbamates, triazoles and pyrethroids by means of an ultrasound-assisted matrix solid-phase dispersion method in fruits and vegetables, employing sand as a solid support [116] . The authors tested different extraction systems (vortex, ultrasonic bath and probe), obtaining the best recovery of pesticides by means of an ultrasonic bath, since this device can accelerate the extraction while presenting less analyte degradation.…”

“…Compared with conventional extraction techniques, MSPD had the advantages of a small amount of solvent and adsorbent consumption, and uncomplicated operation, which saved material consumptions, and greatly reduced the sample processing time [12]. Due to these potential traits, many modified MSPD methods have been widely applied in the determination of additives and pesticide residues in food [13–16], extraction of active compounds in herbal medicine [17–20], detection of dust in the air [21], etc. Various types of solid supports were employed in the literature, including florisil, C 18 , graphene, and silica gel [22–24].…”
