JOURNAL OF HAZARDOUS MATERIALS 2021; 404:124157. [PMID: 33039826 DOI: 10.1016/j.jhazmat.2020.124157] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/06/2020] [Revised: 09/11/2020] [Accepted: 09/29/2020] [Indexed: 06/11/2023]
Abstract
A simple and portable thermometer-type device based on forward osmosis-driven liquid column rising is developed for visual detection of trace Pb2+. The device consists of a top indicator tube, a chamber loaded with Pb2+-responsive poly(N-isopropylacrylamide-co-benzo-18-crown-6-acrylamide) (PNB) smart nanogels and a bottom semipermeable membrane. Upon the recognition of Pb2+, PNB smart nanogels undergo a Pb2+-induced hydrophobic to hydrophilic transition, which simultaneously causes the increase of osmotic pressure inside the device. Driven by this osmotic pressure difference, more Pb2+ solution flows into the device, causing the rise of the liquid column in the indicator tube, which can be directly observed by naked eyes. The relationship between the change of liquid column height and the Pb2+ concentration is investigated for the quantitative detection of Pb2+. With the proposed forward osmosis-driven device, trace Pb2+ as low as 10-10 M in aqueous solutions can be detected. This method provides a novel and simple strategy for the visual detection of trace Pb2+.
