The chosen model analytes toluene, indole, phenol, anisole, <em>o</em>-xylene, naphthalene, 2-heptanone, n-dodecane, and lindane are assigned to different substance classes with K_aw values ranging from -5.0–2.5 and K_ow values from 1.5 to 7.5. The highest amount of the analytes was extracted by the HLB 5 + 30 µm arrow and the HLB 5 µm arrow, whereas the HLB SPME with a six times smaller phase volume compared to an SPME arrow, performed almost as well as the DVB-CWR-PDMS arrow.

Analytical procedures for NQs, sometimes together with their metabolites/by-products, and NQ-related new generation pesticides have been considered, focusing on sample preparation, which is essential in most cases due to both the complexity of the matrices and low concentrations of residual analytes. Different strategies have been practised for analytes extraction/preconcentration/cleanup, entailing various techniques as solid-liquid extraction (SLE), liquid-liquid extraction (LLE), offline and online solid-phase extraction (SPE), dispersive SPE (d-SPE), magnetic SPE (MSPE), solid-phase microextraction (SPME) and the quick, easy, cheap, effective, rugged and safe (QuEChERS) approach. New solid phases, including inorganic and carbon-based materials, have been prepared, also starting from “green” precursors, and successfully employed in the sample treatment step before hyphenated liquid chromatography or direct electrochemical detection. As well, new environmentally friendly solvents have been evaluated for LLE. The most recent studies (2022-present), around 50 papers, have been reviewed by matrix type, briefly described and commented concerning extraction efficiency, matrix effect, sensitivity, ease of application and sample throughput.

It is based on the electrokinetic migration across a membrane under the effect of an external electrical field between two aqueous phases. Trace analysis in complex matrices usually requires an effective sample preparation step to isolate, extract, and enrich the target analytes. Due to its distinctive qualities, including a high degree of enrichment factors, clean-up, and conformity with green chemistry principles, electromembrane microextraction techniques are among the methods for extracting chromium that have gained much attention in recent years. These techniques could be classified into two groups; electromembrane extraction (EME) which is based on using hydrophobic compounds (e.g., a few microliters of organic solvents) to separate the two aqueous solutions (donor and acceptor solutions), and gel electromembrane microextraction (G-EME) which is based on using a membrane made of biopolymers. In this review, the most recent advancements in EME and G-EME technologies for the extraction of chromium species in environmental samples in the last five years were summarized. Furthermore, the performance of the systems is evaluated in terms of their precision and accuracy, detection limits, and merits and drawbacks.
