The results of field studies in 2018 and 2019 at the pilot production site on territory external dump “Zarechny” JSC SUEK-Kuzbass are presented. ecological coenotic characteristics plant communities formed areas with filling fertile soil layer (FSL) (0.5 m thickness), application potentially rocks (PFR) (1 area technogenic eluvium, as well layer-by-layer PFR (0.6 thickness) FSL (0.4 were studie...
in this study, a simple, rapid and selective method was developed for the determination of dexamethasone. the proposed method is based on inhibitory effect of dexamethasone on the oxidation of orange-g by bromate in sulfuric acid media. the reaction was followed spectrophotometrically at 478.5 nm (?max). under optimum experimental conditions, (72.6 ?mol l-1 of orange-g, 0.76 mol l-1 of h2so4, 0...
