The electrochem. behavior of a synthetic B-doped diamond thin film electrode (BDD) was studied in acid media contg. phenol using cyclic voltammetry and bulk electrolysis. In the potential region of H2O stability direct electron transfers can occur on BDD s ...
A promising elimination treatment of non-biodegradable org. pollutants is the direct electro-oxidn. The electrochem. elimination of polyacrylates by using B-doped diamond as anodic material was proposed. The complete elimination of org. contaminants was ob ...
A high molecular weight water soluble graft copolymer having improved flocculating properties is provided. The backbone chain is a heteropolysaccharide comprising amino groups, in particular chitosan, grafted with one or more monoethylenically unsaturated ...
A rapid synthesis of aryl triflate and aryl nonaflate was developed using 4-nitrophenyl triflate and 4-nitrophenyl nonaflate as perfluoroalkanesulfonyl transfer reagents in combination with polymer supported 1,5,7-triazabicyclo[4.4.0]dec-5-ene (PTBD). Simp ...
The electrochem. oxidn. of 3-methylpyridine (3-MP) at synthetic boron-doped diamond (BDD) thin film electrode was studied in acid media by cyclic voltammetry and bulk electrolysis. The results showed that in the potential region of water stability there ca ...
The electrochem. oxidn. of phenol in the presence of NaCl for wastewater treatment was studied at Ti/SnO2 and Ti/IrO2 anodes. The presence of NaCl catalyzes the anodic oxidn. of phenol only at Ti/IrO2 anodes due to the participation of electrogenerated ClO ...
he electrochemical oxidation of phenol for waste water treatment was studied at a platinum anode. Analysis of reaction intermediates and a carbon balance has shown that the reaction occurs by two parallel pathways; chemical oxidation with electrogenerated ...
A review, with 15 refs., on the synthesis, properties, and uses in water and wastewater treatment of poly(dimethyldiallylammonium chloride) [26062-79-3]. [on SciFinder (R)] ...
