Fe(iii) and Cr(vi) ions' removal using AgNPs/GO/chitosan nanocomposite as an adsorbent for wastewater treatment

Abstract

Steps of AgNPs/GO/chitosan nanocomposite preparation.

Adsorption of Mn(ii) ions from wastewater using an AgNPs/GO/chitosan nanocomposite material

“…All column experiment procedures have been done, as in El Shahawy et al (2022). 30 The saturation capacity of adsorbent composites of AgNPs, GO, and chitosan was evaluated in columns using the equation: where q e represents the Mn adsorbed (mg g −1 ), the concentration of Mn in feed water is C o (ppm), and C is the outlet Mn concentration (ppm). The solvent volume needed to achieve the point of exhaustion is known as ve (L), and m is the mass of the adsorbent (g).…”

“…The composite was prepared and synthesized according to El Shahawy et al (2022) 30 (see Fig.1 ). The companies for the purchased and used materials are displayed in Table 1 .…”

“…The S BET surface area was estimated using the BET equation for the adsorption isotherm branch as described by El Shahawy et al (2022). 30 …”

“…These characteristics will contribute to the material's future use as an absorbent for removing heavy metals from industrial wastewater. 29 The main objective of this study was to ascertain the viability of AgNPs/GO/Chitosan Nanocomposite as a low-cost biosorbent for Mn( ii ) adsorption from wastewater. The batch adsorption procedure was examined at room temperature by the following operational parameters: initial pollutant concentration, contact time, adsorbing dose, and stirring rate.…”
