Detection of halide ions

WebJul 5, 2024 · When halide ions were not present in the sample, a single voltammetric peak was obtained due to the oxidation from AgNP to silver (I) ions. However, in the presence of halides, two overlapped voltammetric peaks were obtained, the first one due to silver halides formation on the electrode surface, and the second one due to oxidation from AgNP to … WebHalide perovskites have attracted significant research interests in the X-ray detection and imaging field. Their strong X-ray attenuating ability and good carrier transportation endow them with high sensitivity, which is better than those of commercialized amorphous selenium (a-Se) and CdZnTe (CZT). However, ion migration has been identified as ...
