Abstract

Abstract: This research presents a green synthetic pathway for the preparation of a new biosorbent and eco-friendly extraction process of three phthalate esters: dimethyl phthalate, di-butyl phthalate and benzyl butyl phthalate, from cosmetics and baby care products. Dispersive solid-phase extraction was used based on a new core-shell biomass/sorbent; chitosan-loaded lawsone. The proposed method provides fortunate trapping of phthalate esters in a one-step extraction. Under the optimized extraction conditions, the current work was presented low detection limits (0.03–0.15 ng. g −1 ), limits of quantification (0.1–0.5 ng·g −1 ) and reasonable linearity (0.1–10 000 ng. g −1 ). The applicability of the method was estimated by recovery experiments at different spiking levels ( n = 5) for phthalate esters in the real samples.
