The preparation of ester heterocycles mostly uses heteroatoms as nucleophilic sites, which are achieved by intramolecular substitution or addition reactions. Compound: Cupric bromide( cas:7789-45-9 ) is researched.Name: Cupric bromide.Czompoly, Otto; Borcsok, Endre; Groma, Veronika; Pollastri, Simone; Osan, Janos published the article 《Characterization of unique aerosol pollution episodes in urban areas using TXRF and TXRF-XANES》 about this compound( cas:7789-45-9 ) in Atmospheric Pollution Research. Keywords: aerosol urban air pollution monitoring X ray fluorescence. Let’s learn more about this compound (cas:7789-45-9).
Identifying sources of unique, short-time aerosol pollution episodes in urban areas is a difficult task since they could last only for a couple of hours. With the combination of size-fractioned sampling with May-type cascade impactor and total-reflection X-ray fluorescence (TXRF) in addition to X-ray absorption near-edge structure spectroscopy various sources could be identified in samples collected in Budapest (Hungary) and Cassino (Italy). Using short-time (1-4 h), size-fractionated (70 nm up to 10μm into 7 stages) sampling method, TXRF is capable of detecting transition metals in the order of 0.1 ng/m3. The present study discusses pollution episodes with Cu and Br concentrations in the range of 1-40 ng/m3. The contribution of both exhaust and non-exhaust type traffic-related emission sources were found to be dominant in the Cu species. Wear products of brake system were identified in coarse particles in addition to resuspension of roadside dust. The ratio of organic/inorganic Br could be determined for a pollution episode with elevated Br concentration
As far as I know, this compound(7789-45-9)Name: Cupric bromide can be applied in many ways, which is helpful for the development of experiments. Therefore many people are doing relevant researches.
