Abstract
"REAGENTE PARA A DESTRUIçãO IN-SITU E EX-SITU DE CONTAMINANTES AMBIENTAIS". A presente patente de invenção diz respeito a um reagente utilizado para a destruição in-situ e ex-situ de compostos orgânicos tóxicos e recalcitrantes passíveis de oxidação química que estejam presentes em efluentes industriais, água bruta e tratada, solos, água subterrânea e/ou sedimentos, além também, do uso na oxidação de diversas substâncias inorgânicas, tais como, Mn¬ 2+¬, As¬ 3+¬, Cr¬ 3+¬, NO~ 3~¬ -¬, NO~ 2~¬ -¬ e NH~ 3~, compreendendo a mistura de sais de ferro II (Fe¬ 2+¬) e sais de ferro III (Fe¬ 3+¬), isoladamente ou combinados, na presença de um ou mais ligantes e juntamente com um ou mais agentes tensoativos, em qualquer faixa de pH, e em qualquer relação mássica ¢Fe¬ 2+¬!:¢ligante!: ¢tensoativo!."REAGENT FOR IN-SITU AND EX-SITU DESTRUCTION OF ENVIRONMENTAL CONTAMINANTS". The present invention relates to a reagent used for the in situ and ex situ destruction of toxic and recalcitrant organic compounds liable to chemical oxidation which are present in industrial effluent, raw and treated water, soil, groundwater and / or sediments, as well as the use in oxidation of various inorganic substances such as Mn¬ 2 + ¬, As¬ 3 + ¬, Cr¬ 3 + ¬, NO ~ 3 ~ ¬ -¬, NO ~ 2 ~ ¬ -¬ and NH-3 ~, comprising a mixture of iron II (Fe¬ 2 + ¬) salts and iron III (Fe + 3 + ¬) salts, alone or in combination, in the presence of one or more binders and together with one or more more surfactants, in any pH range, and in any mass ratio ¢ Fe¬ 2 + ¬!: ¢ binder !: ¢ surfactant !.
