Facile Hydrothermal Synthesis of Hierarchical Sodium P Zeolite as a Nonphosphate Detergent Builder

Abstract

This study reports the preparation of hierarchical NaP zeolite with the aim of obtaining a non-phosphate detergent builder as an alternative for environmental remediation from eutrophication phenomenon. Hierarchically structured NaP zeolite was easily synthesized hydrothermally and under different syntheses conditions. Samples were characterized using several standard techniques such as X-ray diffraction (XRD), scanning electron microscopy (SEM), Fourier transform infrared (FT-IR) spectroscopy, and N 2 adsorptiondesorption analysis. Three powder detergents were prepared by mixing main components such as linear alkylbenzene sulfonate, sodium sulfate, sodium silicate, and sodium carbonate as well as different amounts of as-synthesized zeolite and sodium tripolyphosphate in the detergent formulation as potential detergency builders. Some different detergency tests as pH value, water insolubility, foam height, moisture content, alcohol insolubility, and surface tension measurement were carried out for all synthetic detergent samples and two commercial ones. The results demonstrated that the high cleaning performance of the powders was obtained as using ecofriendly zeolite builders in comparison with phosphate-based commercial and synthetic detergent samples.

Calcium Ion Deposition with Precipitated Calcium Carbonate: Influencing Factors and Mechanism Exploration

“…However, applying these methods in detergents remains significant challenges. To overcome challenges and simultaneously enhance the flow property, zeolite has been introduced because of its ability to acts as an ion exchanger to removal metal ions in water and as a surfactant carrier to improve powder flowability [10,11]. However, the non-biodegradability and cost of zeolite have been considered the major problems encountered so far [12].…”

Antibacterial activity of Clinoptilolite/TiO 2 /ZnO photocatalyst against Escherichia coli and Staphylococcus aureus in water resources

“…ZnO causes charge transfer, so it prevents the recombination of electron holes in TiO 2 31 . Supporting materials such as zeolites, crystalline materials with porous structures, play an essential role in photocatalytic processes 32,33 . The two necessary reactants in zeolite synthesis are silicon and aluminum 34 .…”

“…However, this heterogeneity also makes it more complicated to clarify the detailed functions of the pure LAS. So far, LAS mixtures have been extensively studied [29][30][31][32][33], but systematic studies on pure LAS are relatively rare.…”
