The detection and removal of lead (Pb(II)) ions in water is essential for both human health and the natural environment. This study reported the feasibility of the large-pore diameter nano-adsorbent for capturing low level Pb(II) ions from aqueous solutions in a batch system, in order to comply with the toxicity limit for discharging wastewaters. The proposed Pb(II) detection system has good characteristics with high sensitivity and selectivity, robustness, easy operation, portability and use of a small sample volume. The competing ions effect was assessed with spiked samples and the nano-adsorbent exhibited high selectivity to Pb(II) ions with optimum color formation and the detection procedure can be easily applied to rapid on-site Pb(II) ions monitoring.
