Abstract
Arsenic (As) stands as one of the most alarming contaminants, presenting a formidable challenge in the realm of drinking water across numerous countries. To deal with this challenge, the sequestration of arsenic by Adsorption has been extensively investigated in the solid media. Here, a sorbent system based on a polyphenolic network with physical cross-linking using tannic acid and ZrIV ions is investigated for high binding, which is in the form of metal sequestration. The derived solvent system of nano adsorbent molecules was characterized using x-ray diffraction analysis (XRD), energy dispersive x-ray spectroscopic (EDS) and Fourier transform infrared (FTIR) spectroscopic techniques. Adsorption of As was studied under varying governing factors such as pH, adsorbent dosage, and metal ion concentration, and the effects of changing these parameters were documented. Maximum adsorption was observed at solution pH-7, 1 gL−1, and 20 mgL−1 metal ion concentration with removal efficiency reaching up to 95 % in 90 min. Adsorption isotherm and kinetics were studied to deduce the mechanism of adsorption as homogeneous monolayer chemisorption and were best fitted by the Langmuir isotherm model and pseudo-second-order kinetics. Considering the extent of As contamination in the groundwater and the associated health risk to the population, our work provides insides into the nanostructure-dependent capability for As adsorption applications.
