Synthesis and characterization of Alginate-Ag-attapulgite with different ratios of hydroxyapatite nanoparticles

Abstract

In order to enable the in situ bio reduction of Ag ions, our work involves the ecologically friendly creation of a brown attapulgite-Ag nanocomposite using bay leaf extract. This enables good stability and dispersion of Ag NPs together with an effective enhancement in activity and biofriendliness. In order to improve the performance of the alginate-attaplugite-AgNps nanocomposite as an advanced adsorbent material, three different weights (0.1, 0.2, and 0.4 g) of hydroxyapatite nanocomposite were added. The resultant nanocomposite was characterized using XRD, SEM, BET, and TEM. As a result, given its higher bio-performance and cleaner, ecologically friendly production process, the created alginate-attaplugite-AgNps nanocomposite may have significant potential usage in a range of domains, such as food preservation, wound care, and antibacterial or as adsorbent materials.
