Removal of Inorganic Contaminants Using Sodalite Synthesized From Alum Sludge

Particle &Particle Systems Characterization, Volume 43, Issue 5, May 2026.
Alum sludge was successfully converted into sodalite adsorbent through a mild hydrothermal for contaminants adsorption in wastewater. ABSTRACT The growing concern over water contamination by potentially toxic metals underscores the need for sustainable and cost‐effective remediation strategies. In this study, sodalite (SOD‐Na) was synthesized from alum

Zeolite Clinoptilolite: Therapeutic Virtues of an Ancient Mineral [PDF]

Molecules, 2019
Zeolites are porous minerals with high absorbency and ion-exchange capacity. Their molecular structure is a dense network of AlO4 and SiO4 that generates cavities where water and other polar molecules or ions are inserted/exchanged. Even though there are several synthetic or natural occurring species of zeolites, the most widespread and studied is the ...

A critical review of porous adsorbents for air separation: From fundamental insights to rational adsorbent design

AIChE Journal, Volume 72, Issue 4, April 2026.
Abstract Air separation via selective adsorption using porous adsorbents offers energy‐efficient alternatives to cryogenic distillation for producing high‐purity O2 and N2. Adsorbent efficacy depends on balancing selectivity, durability, and performance consistency across varying conditions. This comprehensive review critically discusses the design and

Enhancing Mechanical and Flame‐Retardant Properties of Huntite‐Hydromagnesite Reinforced Polypropylene Composites With Calcite, Zeolite and Intumescent Flame Retardants

SPE Polymers, Volume 7, Issue 2, April 2026.
Thermal behavior of composites reinforced with synergistic materials. ABSTRACT As firefighting efforts increase daily, the use of fire‐resistant materials is also on the rise. However, those materials sometimes create other problems. The discovery that halogenated fire retardants are toxic is one example.

H₂ separation using pressed clinoptilolite and mixed copper‐clinoptilolite disc membranes

The Canadian Journal of Chemical Engineering, 2016
AbstractDisc membranes machined from high‐purity natural clinoptilolite rocks demonstrated promising hydrogen separation efficiency. However, these membranes cannot be adequately scaled up. To overcome this and provide process flexibility, mixed matrix membranes are required, pairing small particles of natural zeolite with a binder system.
