“…As can be seen, some peaks are splitted. It is believed that NaP zeolite framework has two types of unit cell as cubic and tetragonal exhibiting the same XRD patterns and just a slight difference (some doublets in the case of less symmetric tetragonal phase) due to the distortion on the network (Dyer and Molyneux, 1968). Due to the expected positive influence of seeding on the final product purity and shortening of its synthesis time (Koohsaryan and Anbia, 2016), a certain amount of sample P 4 was added to the gel.…”

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.

“…As another hydrophilic zeolitic structures, synthetic NaP zeolite with intersecting channels of 0.31 × 0.44 nm and 0.26 × 0.49 nm was described by Barrer and co-workers for the first time (Dyer and Molyneux, 1968). According to the International Zeolite Association (IZA), the framework topology of NaP zeolite is Gismondine (GIS).…”
