This threat has created the urgency to develop highly efficient adsorbents with both high adsorption capacity and versatile removal of different arsenic compounds. A novel 1D zinc(II) coordination polymer, formulated as Zn2(datrz)2(bpy)Cl2 (BUC-70) (datrz = guanazole, bpy = 4,40-bipyridine), was successfully synthesized through slow evaporation at room temperature. BUC70 exhibited an excellent adsorption capacity toward p-arsanilic acid (p-ASA) and roxarsone (ROX) in water, which could be ascribed to As–O–Zn bonding interactions and strong hydrogen-bonding interactions between the organic arsenics and BUC-70. The maximum adsorption capacities toward p-ASA and ROX were 738 and 937 mg g, respectively. BUC-70 was effective in the removal of p-ASA and ROX at low concentrations (<5 mg l) from the simulated p-ASA and ROX wastewater. Furthermore, the as-synthesized BUC-70 exhibited good adsorption property toward p-ASA and ROX in wastewater simulated by lake water and tap water. After adsorptive treatment using BUC-70, the concentrations of both p-ASA and ROX were lower than the required concentrations of the drinking water standard of the World Health Organization and the surface water standard of China. Continuous-flow, fixed-bed column experiments were performed using BUC-70 loaded on cotton as packing material to explore the potential large-scale application.
