High-efficiency Pb removal by hydroxy-sodalite for point-of-use drinking water purification.
J Hazard Mater
January 2025
Department of Ocean Science and Engineering, Southern University of Science and Technology, Shenzhen, China.
The development of cost-effective point-of-use (POU) devices that effectively remove lead (Pb) from drinking water is imperative in mitigating the threat of Pb contamination to public health in underdeveloped regions. Herein, we have successfully transformed inexpensive natural kaolinite as hydroxy-sodalite (HySOD) via a simple hydrothermal process, achieving an impressive yield of 91.5 %.

Nanoselenium shows potential trends in improving plant health and food quality. In this study, different concentrations of nanoselenium were sprayed on the leaves of alfalfa. Compared to the control, nanoselenium (100 mg·L) significantly increased SeMet and SeMeCys contents in the roots, stems, and leaves of alfalfa.

Article Synopsis
- Selenium is an essential trace element that plays a vital role in human health through its incorporation in selenoproteins, which perform various biological functions, including antioxidant activity and immune system enhancement.
- More than 30 selenoproteins have been identified, with key examples like glutathione peroxidases (GPXs) and thioredoxin reductases (TrxRs) being studied for their health benefits.
- Due to the narrow margin between adequate and toxic doses of selenium, it's crucial to regulate intake levels to prevent deficiencies and toxicity, highlighting its importance in nutritional guidelines and public health.
Evaluation of anion exchange resin for sorption of selenium (IV) from aqueous solutions.
BMC Chem
January 2025
Nuclear Chemistry Department, Hot Laboratories Center, Egyptian Atomic Energy Authority, P.O. 13759, Cairo, Egypt.
In this work, selenium (IV) ions were adsorbed from aqueous solutions by the strongly basic anion exchange resin Amberlite IRA-400. The morphology of the resin before and after Se(IV) sorption was investigated using different techniques such as energy dispersive X-ray spectroscopy (EDX), Fourier transform infrared spectroscopy (FTIR), and scanning electron microscopy (SEM). To determine the ideal sorption conditions, a batch approach was used to examine the variables affecting Se(IV) sorption performance, including pH, shaking time, adsorbent dosage, initial metal ion concentration, and temperature.

Premature ovarian insufficiency (POI) is poorly understood, with causes identified in only 25% of cases. Emerging evidence suggests links between trace elements (TEs) and POI. This study is the first to compare concentrations of manganese (Mn), copper (Cu), zinc (Zn), selenium (Se), molybdenum (Mo), arsenic (As), cadmium (Cd), mercury (Hg), and lead (Pb) across urine, serum, and whole blood in women with POI compared to healthy controls (HC), aiming to explore their distribution and potential associations with POI.
