Abstract

In this work, we report solid-state synthetized defective BiO containing Bi(V) sites as effective and recyclable arsenic adsorbent materials. BiO 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.

摘要

在本研究中，我们报道了通过固态合成法制备的含有Bi(V)位点的缺陷BiO作为有效且可循环利用的砷吸附材料。对BiO进行了广泛的表征，并报道了与结构相关的吸附过程。研究了As(V)和As(III)物种在广泛的浓度、pH值和时间范围内的吸附过程。还测试了几种竞争离子的影响以及吸附剂的可循环性。
