ENGLISH ABSTRACT: A novel sol-gel Ti/Sn02/Sb205 electrode material for the electro catalytic oxidation (combustion) of hazardous organic compounds in water has been designed and characterised. Kinetic studies revealed the mechanism of the combustion reaction. Two reactor systems supporting this catalytic material can be conceived of for application supporting the novel electrode material for water purification, namely: • a Solid Polymer Electrolyte (SPE) sandwich reactor and • a fluidised bed reactor, hosting the electro-catalyst as a powder. An SPE-reactor system has been designed and evaaluated for its performance. As the electrode material seemed to be promising for perchlorate production as well, the oxidation of chlorate to perchlorate was investigated. AFRIKAANSE OPSOMMING: 'n Nuwe sol-gel Ti/Sn02/Sb205 elektrode materiaal vir die elektrokatalitiesie oksidasie (verbranding) van risiko organiese stowwe in water is ontwerp en gekarakteriseer. Kinetiese studies het die meganisme van die verbrandingreaksie getoon. Twee reaktorsisteme vir watersuiwering wat die katalitiese materiaal en die nuwe elektrode ondersteun kan voorgstel word, naamlik: • 'n Soliede Polimeer Elektroliet (SPE) toebroodjiereaktor en • 'n sweefbedreaktor wat die elektro-katalisator as 'n poeier bevat. 'n SPE-reaktorsisteem is ontwerp en nagegaan vir doeltreffendheid. Angesien die elektrode materiaal ook belowend vir perchloraat produksie geblyk het, is die oksidasie van chloraat na perchloraat ook ondersoek.
