The Canadian Journal of Chemical Engineering, EarlyView.Abstract Biostimulants are increasingly used in agriculture to promote plant growth, improve stress tolerance, and support sustainable farming practices. One common method of production is chemical hydrolysis of protein‐rich waste, such as tannery by‐products, offering an economical and eco‐friendly alternative to conventional raw materials.

Experimental methods in chemical engineering: Atomic absorption spectrometry—AAS
The Canadian Journal of Chemical Engineering, EarlyView.Abstract Elements absorb electromagnetic radiation (light) of a specific wavelength in proportion to the number of atoms in its path. As the atoms absorb this light energy, electrons rise from the ground state to an excited state. In atomic absorption spectrometry (AAS), high temperatures produce clouds of atoms from the sample (atomization) and ...

A Fast and Highly Stable Aqueous Calcium‐Ion Battery for Sustainable Energy Storage
ChemSusChem, Volume 18, Issue 6, March 15, 2025.Aqueous batteries provide a low‐cost, safer alternative to lithium‐ion batteries, but their viability is often limited by rapid electrode degradation. This study shows that replacing K+ with divalent Ca2+ ions in the electrolyte significantly boosts the stability of both copper hexacyanoferrate cathodes and polyimide anodes, enabling fast‐charging ...

Chemotherapy, 2000
The antibacterial activity of metal ions, metal chelates, and molecules with chelating ability for polyvalent cations have been evaluated. The chelator N,N′-ethylenebis[2-(2-hydroxyphenyl)-glycine] (EHPG) exerted moderate-to-good activity against isolates of pathogenic bacteria and fungi. Other chelating agents such as ethylenediamine-tetraacetic acid (

Journal of Toxicology: Clinical Toxicology, 1982
AbstractIn recent years there has been a growing awareness of the importance of trace metals in the environment, in their dichotomous role as essential nutritional factors on the one hand, and as toxic agents on the other. The apparent ambivalent nature of metal ions is shown as a continuum in a wide range dose-response curve. The response on the curve,

Chelating Agents for Metal Intoxication
Current Medicinal Chemistry, 2012In this paper we took into examination the use of chelation therapy for treating metal intoxication in humans. We divided this paper in four main parts: before all the principal causes of toxicity are exposed; second the chemical requirements (thermodynamic and kinetic), the interactions with the endogenous molecules and the target organs, as well as ...

The problem of chelating agents used as antidotes in intoxications with metals is intensively studied during the past 20 years. Due to the complex nature of the action of these substances in the organism their investigation is a typically interdisciplinary problem. The submitted review gives the theoretical background of the formation of chelate in the
