Liquid phase microextraction (LPME) has been widely used in extraction and preconcentration systems as an excellent alternative to conventional liquid phase extraction. In this work, a critical review is presented on liquid phase microextraction techniques used in the determination of cadmium in environmental samples. LPME techniques are classified into three main groups: single-drop liquid phase microextraction (SDME), hollow fiber liquid phase microextraction (HF-LPME), and dispersive liquid-liquid microextraction (DLLME). Methods involving these liquid phase microextraction techniques are described, addressing advantages and disadvantages, samples, figures of merit, and trends.
液相微萃取（LPME）作为传统液相萃取的一种绝佳替代方法，已在萃取和预浓缩系统中得到广泛应用。本文对用于测定环境样品中镉的液相微萃取技术进行了批判性综述。LPME技术主要分为三大类：单滴液相微萃取（SDME）、中空纤维液相微萃取（HF-LPME）和分散液液微萃取（DLLME）。文中描述了涉及这些液相微萃取技术的方法，讨论了其优缺点、样品、性能指标及发展趋势。
