A new thiazole substituted chemosensor 1 has been designed and synthesized for selective detection of fluoride ions. The chemosensor 1 was characterized by 1H NMR and 13C NMR. The absorption studies of chemosensor in DMF exhibits two peaks at 283 nm and 327 nm. The anion sensing behaviour of chemosensor 1 for various anions (I-, Cl-, Br-, NO3-, HSO4-, PF6-, ClO4-) in DMF were investigated by UV-vis spectroscopy. Chemosensor 1 exhibited high degree of selectivity for fluoride ions over other anions. A good linearity in the range of 16-133 μM with 6.12 μM limit of detection value (LOD) was observed.

(1) For the first time a terpyrideine-Cu(ii) complex was used for the selective detection of F− ions. (2) A dual mode detection method comprising chromo-luminescent techniques was used to evaluate the sensing mechanism. (3) The limit of detection was found to be 5.07 μM which is within the permissible level of F− ions in drinking water according to the WHO.

AbstractIn this proposed work, direct green 6 (DG6) decorated carbon paste electrode (CPE) was fabricated for the efficient simultaneous and individual sensing of catechol (CA) and hydroquinone (HY). Electrochemical deeds of the CA and HY were carried out by cyclic voltammetry (CV) and differential pulse voltammetry (DPV) at poly-DG6-modfied carbon paste electrode (Po-DG6-MCPE). Using scanning electron microscopy (SEM) studied the surface property of unmodified CPE (UCPE) and Po-DG6-MCPE. The decorated sensor displayed admirable electrocatalytic performance with fine stability, reproducibility, selectivity, low limit of detection (LLOD) for HY (0.11 μM) and CC (0.09 μM) and sensor process was originated to be adsorption-controlled phenomena. The Po-DG6-MCPE sensor exhibits well separated two peaks for HY and CA in CV and DPV analysis with potential difference of 0.098 V. Subsequently, the sensor was practically applied for the analysis in tap water and it consistent in-between for CA 93.25–100.16% and for HY 97.25–99.87% respectively.
