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 obtained and this is the first case of successful electrochem. treatment of polymeric and bio-refractory species. The tests of the electrochem. oxidn. were conducted at const. current conditions and a complete elimination of org. species was reached. The decrease of the COD value with time follows the behavior of an ideal anode as in the case of low mol. org. compds. [on SciFinder (R)]
