Laser-induced fluorescence spectroscopy was used to detect mercury ions in aqueous solutions, which CH-95 resin chelate the transform liquid samples into solid ones. The experimental results showed that emission of chelated solid-state excited by a low-power semiconductor laser at wavelength 447 nm significantly enhanced due chelating reaction. intensity proportional concentration with linear correlation coefficient R 2 = 0.994, and limit detection 0.117 ng/L, about 10,000 times lower than permissible level 1 µg/L for Hg(II) drinking water. method greatly improved sensitivity Hg solutions.

Mercury(II) is highly toxic thus the selective and sensitive detection of Hg(II) important. This research article deals with synthesis characterization fluorogenic system based on diselenide containing rhodamine by single crystal XRD. The probe has been used for in aqueous media limit 62.3 nM. reaction induces opening spirolactam ring triggering fluorescence turn-on response. causes color change solution from colorless to pink. In addition, showed reversible binding behavior S2-. effectiveness was evaluated using prostate cancer cell line through live imaging.
