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.

以劳松封端壳聚糖为基础的生物吸附剂液相色谱法测定化妆品和婴儿护理用品中的邻苯二甲酸酯

本研究为从化妆品和婴儿护理产品中制备三种邻苯二甲酸酯（邻苯二甲酸二甲酯、邻苯二甲酸二丁酯和邻苯二甲酸苄基丁酯）的新型生物吸附剂和环保提取工艺提供了一条绿色合成途径。采用基于新型核壳生物质/吸附剂的分散固相萃取；壳聚糖负载的lawone。所提出的方法在一步萃取中提供了邻苯二甲酸酯的幸运捕获。在优化的提取条件下，目前的工作呈现出低检测限（0.03-0.15 ng.g-1）、定量限（0.1-0.5 ng·g-1）和合理的线性（0.1-10 000 ng.g- 1）。该方法的适用性是通过对实际样品中邻苯二甲酸酯在不同加标水平 (n = 5) 下的回收率实验来估计的。
