“…Although traditional techniques have been applied widely to detect Ag + ions in environmental samples, such as gas chromatography and liquid chromatography [ 4 ], atomic absorption/emission spectroscopy [ 5 ], electro thermal atomic absorption spectrometry [ 6 ], Inductively Coupled Plasma-Mass Spectrometry (ICP-MS) [ 7 ] and Inductively Coupled Plasma-Atomic Emission Spectrometry (ICP-AES) [ 8 ], they require expensive and sophisticated instrumentation and/or time-consuming and complicated sample preparation processes [ 9 ]. Therefore, they are not well suited for rapid on-site detection of Ag + ions.…”

This study presents chemical modification of a Rhodamine B (RhB) sensor probe by ethylenediamine (EDA), and investigation of its spectral as well as sensor properties to the various metals. The synthesised N-(Rhodamine-B)-lactam-ethylenediamine (RhB-EDA) fluorescent probe shows interesting optical sensor properties, and high sensitivity and selectivity to Ag+ ions among all the tested metal ions (K+, Mg2+, Cu2+, Ni2+, Fe2+, Pb2+, Na+, Mn2+, Li+, Al3+, Co2+, Hg2+, Sr2+, Ca2+, Ag+, Cd2+ and Zn2+), while the well-known Rhodamine B (RhB) fluorescent probe shows much less sensitivity to Ag+ ions, but high sensitivity to Fe2+ ions. The novel fluorescent sensor probe RhB-EDA has the capabilities to sense Ag+ ions up to µM ranges by using the fluorescence quenching approach. The probe displayed a dynamic response to Ag+ in the range of 0.43 × 10−3–10−6 M with a detection limit of 0.1 μM. The sensing system of an RhB-EDA novel fluorescent probe was optimised according to the spectral properties, effect of pH and buffer, photostability, incubation time, sensitivity, and selectivity. Since all the spectral and sensing properties were tested in green aqueous media, although many other similar sensor systems rely on organic solvent solutions, the RhB-EDA sensing probe may be a good candidate for measuring Ag+ ions in real-life applications.

Specific recognition of ultratrace levels of ions in semi-water using super-quicker methods is still a challenge for environmental monitoring. Herein we report a fluorescent and colormetric sensor (ZH) based on supramolecular self-assembly, whose structure was destroyed by the addition of ultratrace of silver ions. The process promoted either naked eye visible color changes or fluorescence intensity quenched in conjunction with a wide pH range. Systematic studies revealed very high selectivity (0.07 μmol/L) for silver ions, and other common cations, e.g., Hg 2＋ , Cu 2＋ , Cd 2＋ , Pb 2＋ had nearly no influence on the sensing behavior. This sensor also served as a multiple use of component in sensing materials by addition of I  into the mixture of ZH and Ag ＋ (about 5 times). What's more, ZH containing filter paper emerged distinct color and fluorescence changes upon exposure to silver (Ag ＋ ), which could be used as a portable method to undertake field testing for Ag ＋ .

A sensitive, reliable, and environmentally friendly method for simple separation and preconcentration of Ag(I) traces in aqueous samples is presented prior to their flame atomic absorption spectrometric determinations. At pH 7.0, Ag(I) was separated with 2‐(2‐methoxyphenyl)benzimidazole (MPBI) as a new complexing agent and floated after adding sodium dodecyl sulfate (SDS) as a foaming reagent. The floated layer was then dissolved in proper amount of concentrated nitric acid in methanol and introduced to the flame atomic absorption spectrometer (FAAS). The effects of pH, concentration of MPBI, type and amount of surfactant as the floating agent, type and amount of eluting agent, and influence of foreign ions on the recovery of the analyte ion were investigated. Also, using a nonlinear curve fitting method, the formation constant of 1.62 × 106 was obtained for Ag(I)–MPBI complex. The analytical curve was linear in the range of 1.8 × 10−7–1.7 × 10−6 mol/L for determination of Ag(I). The relative standard deviation (RSD; N = 10) corresponding to 0.7 × 10−6 mol/L of Ag(I), the limit of detection (10 blanks), and the enrichment factor were obtained as 1.7%, 2.9 × 10−8 mol/L, and 43.0, respectively. The proposed procedure was then applied successfully for determination of silver ions in different water samples.
