Adsorption and competitive adsorption of heavy metal ions lead, cadmium and copper on d-manganese oxide

Chemistry Magazine Online gives you another post with interesting chemistry news articles. Abstracts d- MnO2 was prepared with hydrothermal treatment, and its crystalline structure was verified with X-ray diffraction spectroscopy. FTIR showed there were copious hydroxyl groups on the surface of d-MnO2 for the adsorption. The adsorption capacity of three kinds of heavy metal ions Pb2+, Cd2+ and Cu2+ on the d-MnO2 was …

Synthesis and characterization of Fire retarded poly (DAMT -co-acrylonitrile)

Abstract In this paper diethoxy-acrylamide methoxyl thiophosphate (DAMT) was synthesized with the reaction N-hydroxymethyl acrylamide and O, O-diethyl phosphorochloridothioate catalyzed by cuprous chloride in presence of triethylamine, and the flame retarded poly (DAMT-co-acrylonitrile) was obtained though free-radically copolymerized process. The properties of copolymer were estimated by Limiting Oxygen Index (LOI) values and thermogravimetric analysis (TGA). The …

Cure Kinetics of Epoxy Resin/MP/Anhydride/Accelerant Flame Retardant Composite

Abstract Cure kinetics of epoxy resin E51/MP/methyltetrahydrophthalic anhydride (MeTHPA)/ 2-ethyl-4-methyl-imidazole (2,4-EMI) flame retardant composite were studied using the dynamical tortional vibration method. The influence of MP loadings on The cure showed has improved studied were well. The results showed that the rate of cure reactions depended distinctly on the cure temperature. At low MP loadings, the …
