Biphasic Extraction of Selected Heavy Metals From Corn With the Aid of Kosmotropic Salts

open access: yesAnalytical Science Advances, Volume 7, Issue 2, December 2026.
ABSTRACT This study investigated the use of aqueous two‐phase extraction (ATPE) with kosmotropic salts for the extraction of toxic heavy metals from maize. Heavy metals, such as cadmium (Cd), chromium (Cr) and iron (Fe), are harmful to human health because they accumulate in the food chain and may cause kidney damage, cancer and nervous system problems.

Schiff Base‐UiO66 Composite‐based Dispersive Micro Solid‐Phase Extraction of Pesticides From Fruit Juices Combined With Dispersive Liquid‐Liquid Microextraction Prior to Gas Chromatography‐Flame Ionisation Detection

open access: yesAnalytical Science Advances, Volume 7, Issue 2, December 2026.
ABSTRACT A dispersive micro solid‐phase extraction method was introduced using a Schiff base‐UiO66 nanocomposite as the adsorbent in the extraction of multi‐class pesticide residues in pear, cherry, grape, and apricot juices. The extraction procedure was hyphenated with a liquid‐phase microextraction procedure, providing a high preconcentration factor ...

Beyond Total Content: Assessing the Bioaccessibility of Metals in Tattoo Inks Using Validated Extraction Media

open access: yesAnalytical Science Advances, Volume 7, Issue 2, December 2026.
ABSTRACT A validated analytical workflow is presented for determining total and bioaccessible concentrations of regulated elements in tattoo inks, addressing the lack of harmonized protocols for comparing extraction approaches in complex matrices. Although current legislation defines limits for soluble fractions of selected metals, it does not specify ...

A Dual GC–MS and LC–MS/MS Analytical Strategy for Evaluating Free Chlorine Toxicity in Aqueous Samples

open access: yesRapid Communications in Mass Spectrometry, Volume 40, Issue 20, 30 October 2026.
ABSTRACT Rationale Chlorine gas is a highly toxic industrial chemical that poses a significant risk in accidental releases and deliberate terrorist attacks. Reliable analytical methods for the determination of chlorine in aqueous samples are therefore required for forensic and environmental investigations.
