A new solid‐phase adsorbent was synthesized for the simultaneous enrichment of multiple classes of trace insecticides (neonicotinoids, organophosphates, fiproles, and organochlorines) in water. The adsorbent was spherical with a diameter, surface area, average pore volume, and pore size of approximately 5 μm, 341 m2/g, 0.092 m3/g, and 2.22 nm, respectively. Extraction conditions were optimized, including...
An aqueous solution of polyethylene glycol (PEG) as a green solvent was employed for the first time to develop the ultrasound‐assisted extraction of proanthocyanidins (PA) and chlorogenic acid (CA) from almond skin. The optimized extraction parameters were determined based on response surface methodology, and corresponded to an ultrasound power of 120 W, a liquid‐to‐solid ratio of 20:1 (mL/g), and...
