In recent decades, environmental pollution has become a significant problem for human health and impact. The high accumulation of heavy metals in waters soils from different sources was conducted finding efficient environmentally friendly treatment methods materials their removal, respectively. Natural zeolites have found wide-ranging applications remediation protection, considering various modification designed to enhance the natural zeolites' adsorptive or ion-exchange capabilities increased efficiency. This paper briefly consolidates scientific literature related main characteristics modified zeolites, advantages limitations applying remediation, summarizes methodologies applied order improve properties. Their application removing water systems is also comprehensively discussed. review highlights excellent potential be used after specific as sustainable green material solve numerous issues.

Synthesis of BiOX-Red Mud/Granulated Blast Furnace Slag Geopolymer Microspheres for Photocatalytic Degradation of Formaldehyde

Materials, Journal Year: 2024, Volume and Issue: 17(7), P. 1585 - 1585

Published: March 30, 2024

Release of formaldehyde gas indoors is a serious threat to human health. The traditional adsorption method not stable enough for removal. Photocatalytic degradation effective and rapid, but photocatalysts are generally expensive easy recycle. In this paper, geopolymer microspheres were applied as matrix materials loading degrade formaldehyde. Geopolymer prepared from red mud granulated blast furnace slag raw by alkali activation. When the doping was 50%, concentration NaOH solution 6 mol/L, additive amount 30 mL, possessed good morphological characteristics large specific surface area 38.80 m2/g. With BiOX (X = Cl, Br, I) on microspheres, 85.71% adsorbed within 60 min. rate loaded with BiOI reached 87.46% 180 min, which 23.07% higher than that BiOBr, 50.50% BiOCl. While ensuring efficient formaldehyde, I)-loaded recycle can save space. This work only promotes resource utilization slag, also provides new idea formation catalysts in process photocatalytic
