Detection of trace levels of Pd2+ in pure water using a fluorescent probe assisted by surfactants

To accurately monitor a trace amount of palladium species in water system is both medically and environmentally important. However, up to now, it remains a challenge for the probes to detect palladium ions in pure water sample. In this contribution, we disclosed a novel detection method based on surfactant assisted fluorescence amplification strategy for Pd2+ detection in pure water. Among of five selected surfactants, Triton X-100 exhibited best sensing properties, such as high selectivity and excellent sensitivity. This work provided a promising design principle for hydrophobic fluorophore-based probes applied in pure water detection. (C) 2016 Elsevier B.V. All rights reserved.
