The optimal conditions of complex formation between boric acid and dibenzoylmethane are investigated, luminescence spectral caracteristics of the solutions of the complex are described, and the phosphorescence mean lifetime of the dibenzoylmethane‐boric acid system is evaluated. Analytical curves, established by fluorimetry and phosphorimetry, are satisfactory. 0.0005 μg B/ml is the minimum detectable concentration.</p> Dewey 540 40 Département de chimie minérale, analytique et appliquée 145 false Helvetica chimica acta 52 2 626a8681-4a7d-4ce0-856a-4a4c516dac34 Article (Published version) Restricted Marcantonatos_HCA_196952538.pdf 313952 application/pdf 61c9fe08841e63e3b03b059653b7c656ec4dd62b138192e67d65869bd6b8430c restrictedAccess Faculté des sciences / Section de chimie et biochimie / Département de chimie minérale, analytique et appliquée
