“…[75] The prepared g- poly(BPE)/g-C 3 N 4 composites were used in the simultaneous detection of Cd 2+ and Pb 2+ . [76] The conduction path on the surface of the working electrode was improved by the combination of poly(BPE) and g-C 3 N 4 , which provided a strong conjugating effect, promoting the adsorption of metal ions. and 0.00324 µM for Cd 2+ and Pb 2+ , respectively.…”

In recent years, graphitic carbon nitride (g-C 3 N 4) has attracted much attention due to its unique properties and excellent performance in the field of sensors, which has inspired the authors to compile this review. Although there are many reviews on the synthesis and applications of g-C 3 N 4 materials, a targeted, systematic, comprehensive summary of applications in sensors and the sensing mechanisms of g-C 3 N 4-based nanomaterials have not been published. In this review, the preparation methods and synthetic conditions for preparing g-C 3 N 4 with different morphologies, such as conventional bulk g-C 3 N 4 , g-C 3 N 4 nanosheets, and g-C 3 N 4 quantum dots, are introduced in detail. By reviewing recent advances in g-C 3 N 4-based nanomaterials in ion sensors, biosensors, gas sensors and humidity sensors, this study provides more comprehensive and in-depth information for the further design of g-C 3 N 4based sensors with enhanced performance. A brief outlook of g-C 3 N 4-based sensors is presented as the conclusion of this review.

Drinking water contamination of lead from various environmental sources, leaching consumer products, and intrinsic water-pipe infrastructure is still today a matter of great concern. Therefore, new highly sensitive and convenient Pb2+ measurement schemes are necessary, especially for in-situ measurements at a low cost. Within this work dye/ionophore/Pb2+ co-extraction and effective water phase de-colorization was utilized for highly sensitive lead measurements and sub-ppb naked-eye detection. A low-cost ionophore Benzo-18-Crown-6-ether was used, and a simple test-tube mix and separate procedure was developed. Instrumental detection limits were in the low ppt region (LOD = 3, LOQ = 10), and naked-eye detection was 500 ppt. Note, however, that this sensing scheme still has improvement potential as concentrations of fluorophore and ionophore were not optimized. Artificial tap-water samples, leached by a standardized method, demonstrated drinking water application. Implications for this method are convenient in-situ lead ion measurements.
