Efficient extraction of pollutants with different chemical properties from environmental
samples has attracted great attention in the development of analytical chemistry. However, it …

Abstract Background Polycyclic aromatic hydrocarbons (PAHs) are an important class of
potentially toxic persistent organic pollutants in environmental water. Their concentrations …

Zeolitic imidazole framework-67 (ZIF-67) derived hollow nanomaterials (HO-ZIF-67) were
prepared by an etching technique of tannic acid and used as solid-phase microextraction …

An efficient and stable adsorbent is of critical importance for solid-phase microextraction
(SPME). In this study, we prepared metal–organic framework-derived nitrogen (N)-doped …

While a growing number of solid-phase microextraction (SPME) coatings have been
developed, a generalized protocol is still needed to tailor-make SPME coatings with …

Herein, a novel solid-phase microextraction (SPME) fiber based on hollow carbon
nanobubbles was developed for the analysis of persistent organic pollutants. The hollow …

Developing novel coating materials for fast and sensitive solid-phase microextraction
(SPME) is highly desired but few are achieved. In this work, a new material of metal–organic …

In this work, hierarchical ZIF-8 coated anodized aluminum foil was prepared through in situ
template-directed method without addition of any zinc salt. The hierarchical sorbent was …

In this paper, we have, for the first time, proposed an approach by combining self-assembled
monolayers (SAMs) and nanomaterials (NMs) for the preparation of novel solid-phase …

Abstract Lotus-like Ni@ NiO embedded porous carbons (Ni@ NiO/PCs) were fabricated by
pyrolysis of MOF-74/cellulose nanocrystal hybrids, and used as a solid phase …
