Their characterization was realized by help of instrumental techniques. The method is based on pH-dependent complexation between As(III) and copolymeric chelators in presence of 35-fold excess As(V), their selective extraction into the mixed micellar phase, and detected at pH 2.0 and 6.0 by UV–vis spectrophotometer. The variables affecting extraction efficiency were optimized. From pre-concentration of 20-mL sample, the good linear relationships were obtained in range of 1–40 and 3–75 μg/L with DLs of 0.32 and 1.00 μg/L. The accuracy was verified by analysis of a certified sample without and with spiking. The method was applied into the analysis of iAs levels of samples. The results show that the functional co-polymers are efficient chelators, and exhibit great potential for the selective extraction of As(III) from edible vegetable oils.en10.1016/j.foodchem.2022.135335info:eu-repo/semantics/openAccessAs(III) 2-HBT/poly(MAnh) CTAB/SDS Edible vegetable oils Pre-concentration UV–vis spectrophotometryAnimation409135335135335365992922-s2.0-85145350271Q1WOS:000964096200001Q1
