Defective Bismuth Oxide as Effective Adsorbent for Arsenic Removal from Water and Wastewater

Abstract

In this work, we report solid-state synthetized defective Bi2O3 containing Bi(V) sites as effective and recyclable arsenic adsorbent materials. Bi2O3 was extensively characterized, and structure-related adsorption processes are reported. Both As(V) and As(III) species-adsorption processes were investigated in a wide range of concentrations, pH values, and times. The effect of several competing ions was also tested together with the adsorbent recyclability.

Electrodes for Paracetamol Sensing Modified with Bismuth Oxide and Oxynitrate Heterostructures: An Experimental and Computational Study

“…According to data reported by Gadhi et al [23], pure Bi O NO (Figure 2a) has a structure characterized by flower-like particles composed of interconnected planes of few nanometers in thickness. B600 showed a partial sinterization of pure Bi O grains due to the high calcination temperatures (Figure 2b) as was reported by Balint et al [35].…”
