Simple Summary Rare earth elements (REEs) have become important metals in modern-
day technology. The process of discarding obsolete equipment containing REEs, use of …

In this era of rapid industrialization and modernization, contamination of the environment
with heavy metals from natural and anthropogenic sources without proper disposal …

Labile metals in agricultural soils are available to crops and thus pose a great health risk for
human beings. Therefore, factors influencing heavy metal activity are of interest to …

This research aimed to evaluate the capacity of acid-resistant purple nonsulfur bacteria,
Rhodopseudomonas palustris strains VNW02, TLS06, VNW64, and VNS89, to resist Al 3+ …

Metal speciation studies can be performed with a new technique based on a functionalized
membrane. The estimation of not only the total amount of metal, but also the metal available …

In this study, a lignin-based adsorbent modified with epichlorohydrin and
pentaethylenehexamine (LO-PEHA) was controllably synthesized via epoxidation and …

As a low-cost adsorbent, sepiolite has been used for the adsorption of Fe (II) and Fe (III) from
aqueous solutions. The proposed method was applied to the determination of iron in tap …

Background In the river system, the geochemistry of rare earth elements (REEs, a series of
elements from La to Lu) in suspended particulate matter (SPM) is generally controlled by …

Purpose The geochemistry of rare earth elements (REEs, La to Lu) in suspended sediments
(SS) is generally controlled by weathering processes and the water environment. Although …

Abstract Free concentrations of Zn 2+, Fe 3+, Ca 2+ and Mg 2+ in a red wine (Raimat,
Catalonia, Spain) have been determined, with the Donnan Membrane Technique (DMT) for …
