TLDR
A comprehensive review of liquid liquid microextraction (DLLME) techniques for analysis of trace emerging pesticides in water is presented in this paper, where thin-layer stripping voltammetric techniques at surface modified electrodes and spectrofluorimetric techniques coupled and implemented with DLLME are discussed.Abstract:
Dispersive liquid-liquid microextraction (DLLME) techniques have attracted considerable interest because they are cost effective, easy to operate, and reliably preconcentrate trace levels of analytes in complex matrices. This comprehensive review is concerned with principles, applications and developments of DLLME techniques for analysis of trace emerging pesticides in water. DLLME techniques have had few couplings to spectrofluorimetric methods and relatively none with electrochemical techniques. We highly recommend thin-layer stripping voltammetric techniques at surface-modified electrodes and spectrofluorimetric techniques coupled and implemented with DLLME. Great attention should be focused on developing low-cost, precise methods for analysis of trace concentrations of pesticides in various biological and environmental samples. We describe milestones and the combination of nanotechniques in the DLLME field, green aspects, advantages and shortcomings of known DLLME protocols.read more
