Ultrafiltration based on the use of co-polyelectrolytes bearing carboxyl, sulfonate, and tertiary amino groups was used to investigate removal of divalent ions from aq. solns. The efficiency of metal sepn. was evaluated for model solns. of Cu2+, Zn2+, Mn2+ ...
The electro-oxidn. of 1,4-benzoquinone in water soln. was investigated. The benzoquinone concn., intermediate products, dissolved org. C (DOC), COD, and toxicity of the oxidized soln. was monitored during oxidn. with Ti/IrO2 and Ti/SnO2 anodes (in the foll ...
Electrochem. oxidn. (or combustion) of orgs. with simultaneous O evolution was investigated using different electrode material (Pt, Ti/IrO2, Ti/SnO2). A simplified mechanism for org. electrochem. oxidn./combustion is presented according to which selective ...
A simple method is presented which allows to est. the facility of the electrochem. oxidn. of org. species using the "electrochem. oxidn. index" (EOI) and the degree of oxidn. using the "electrochem. oxygen demand" (EOD). Using this method the authors have ...
The electrochem. oxidn. of phenol for wastewater treatment was studied on doped SnO2 anodes. Anal. of reaction intermediates and a C balance showed that the main reaction is oxidn. of phenol to CO2. This unexpected behavior of the SnO2 anode is explained b ...
Electrochem. oxidn. of org. compds. in industrial wastewaters preceding or following a biol. treatment is described. Definitions of parameters are given, including various parameters influencing the efficiency of electrochem. oxidn. of org. compds. (IOE). ...
A process for catalytic oxidation of organic materials in waste water by hydrogen peroxide in the presence of iron (III) salts at temperatures below 80 DEG in the presence of titanium dioxide and with exposure to light. ...
A review with 21 refs. on the strategy of wastewater treatment in org. chem. industry. Biodegradability tests, toxicity tests, aerobic and anaerobic treatment processes, and electrochem. oxidn. of org. substances are discussed with an example of a pilot pl ...
The aim was to examine the anodic oxidn. of some benzene derivs. (model org. pollutants) at Pt and DSA (dimensionally stable anodes) type anodes to elucidate the possibilities of the electrochem. method and to elucidate the mechanism of the reaction. ...
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 ...
