Abstract
Patente de Invenção:<B>"MéTODO DE PREPARO DO H~ 2~S PARA UMA ANáLISE ISOTóPICA"<D>. Método que permite preparar o enxofre e/ou o hidrogênio contidos em pequena quantidade no hidrofênio sulfurado: 1) realiza-se a oxidação do H~ 2~S a uma temperatura e uma duração escolhidas de forma a se conseguir a oxidação total do H~ 2~S em SO~ 2~, e conseguem-se, ao final dessa etapa, pelo menos dois produtos: SO~ 2~ e H~ 2~O; 2) separam-se os dois produtos SO~ 2~ e H~ 2~O conseguidos ao final da etapa 1); 3) faz-se a medida isotópica do enxofre contido no dióxido de enxofre obtido na etapa 2), e/ou 4) coloca-se em contato o H~ 2~O obtido na etapa 2) com um agente capaz de reduzir a água sob a forma de hidrogênio; e 5) faz-se a medida isotópica do hidrogênio.
