The degradation of fluorene, a toxic and carcinogenic substance formed by combustion of fossil fuels, was studied in alkaline, aqueous solution. It is very efficiently decomposed by ozonation, where 9-fluorenone and 9-fluorene carboxylic acid appear as major products in addition to a mixture of aldehydes and carboxylic acids. A more efficient substrate decomposition was observed by a treatment with γ-rays in the presence of ozone. The yield of the main products was in the case 4-times lower compared to those obtained by ozonation only. Some probable reaction steps are presented for explanation of the products.
