Adsorption of ng L^-1-level arsenic by ZIF-8 nanoparticles: application to the monitoring of environmental water.

ABSTRACT: The provisional contamination level of arsenic in drinking water is 10 μg L^-1. For decreasing this value to a safer level, a more precise method for analyzing dissolved arsenic is required. With this aim, we synthesized zeolitic imidazolate framework-8 (ZIF-8) in the aqueous phase and characterized its potential application for monitoring the trace arsenic in fresh water. In this regard, we report following three notable outcomes. First, we demonstrate the excellent performance of ZIF-8 nanoparticles (nZIF-8) for the adsorption of ng L^-1 levels of AsO₄ ^3-. nZIF-8 is able to adsorb over 99% of arsenic from as low as 10 ng L^-1 AsO₄ ^3- solutions. This performance was maintained even in the presence of commonly coexis
