Abstract

"PROCESSOS PARA A PREPARAçãO DE SOLUçõES DE HIDROXILAMINA ESTABILIZADAS, DE ALTA PUREZA, E, PARA REDUZIR AS CONCENTRAçõES DE âNION NAS SOLUçõES AQUOSAS DE HIDROXILAMINA". A invenção diz respeito a um método para preparar soluções de hidroxilamina altamente estabilizadas. De acordo com o dito método, uma solução de partida aquosa de hidroxilamina é tratada para separar ânions por meio de um trocador de ânion que foi completamente carregado com um estabilizante de hidroxilamina.
