Abstract

A green, efficient, and cost-effective bio-derived solvent-based automated dispersive liquid–liquid microextraction (BDS-ADLLME) method was developed in the present study. A liquid handling platform with only the pipetting function module was employed to achieve automated multiple-sample pretreatment and eliminate manual errors. Green bio-derived solvents, γ-valerolactone and eucalyptol, derived from renewable resources and exhibiting high environmental friendliness, were used as dispersant and extractant, respectively. The eucalyptol self-separated from the samples within 5 minutes, eliminating the need for centrifuges and demulsifiers. Four greenness evaluation tools confirmed that the BDS-ADLLME was an environmentally friendly sample pretreatment method meeting the requirements of green chemistry. The linear range was 0.006–3 μg L⁻¹ with R² > 0.999. The limit of detection was 0.002 μg L⁻¹. The BDS-ADLLME method successfully detected chlorantraniliprole and flubendiamide in tap, river, lake, and spring water samples, with recoveries and relative standard deviations ranging from 83.4–107.7% and 1.7%–5.4%, respectively. The BDS-ADLLME provides a feasible approach for developing automated eco-friendly dispersive liquid–liquid microextraction methods.

生物溶剂型自动分散液-液微萃取法预处理环境水样中二胺类杀虫剂

本研究建立了一种绿色、高效、经济的生物溶剂基自动分散液液微萃取（BDS-ADLLME）方法。采用仅带移液功能模块的液体处理平台，实现多样品自动化预处理，消除人工误差。采用绿色生物衍生溶剂γ-戊内酯和桉树醇分别作为分散剂和萃取剂。桉树精油在5分钟内从样品中自行分离，不需要离心机和破乳剂。四种绿色度评价工具证实了BDS-ADLLME是一种符合绿色化学要求的环境友好型样品前处理方法。线性范围为0.006 ~ 3 μg L−1,R2 >；0.999. 检出限为0.002 μ L−1。BDS-ADLLME方法成功检测自来水、河流、湖泊和泉水样品中的氯虫腈和氟虫胺，回收率为83.4 ~ 107.7%，相对标准偏差为1.7% ~ 5.4%。BDS-ADLLME为开发自动化的生态友好型分散液液微萃取方法提供了可行的途径。

期刊介绍： Green Chemistry is a journal that provides a unique forum for the publication of innovative research on the development of alternative green and sustainable technologies. The scope of Green Chemistry is based on the definition proposed by Anastas and Warner (Green Chemistry: Theory and Practice, P T Anastas and J C Warner, Oxford University Press, Oxford, 1998), which defines green chemistry as the utilisation of a set of principles that reduces or eliminates the use or generation of hazardous substances in the design, manufacture and application of chemical products. Green Chemistry aims to reduce the environmental impact of the chemical enterprise by developing a technology base that is inherently non-toxic to living things and the environment. The journal welcomes submissions on all aspects of research relating to this endeavor and publishes original and significant cutting-edge research that is likely to be of wide general appeal. For a work to be published, it must present a significant advance in green chemistry, including a comparison with existing methods and a demonstration of advantages over those methods.
