Abstract
"PROCESSOS PARA REMOVER ARSêNICO PENTAVALENTE DE UMA SOLUçãO AQUOSA, PARA OXIDAR ARSêNICO TRIVALENTE EM ARSêNICO PENTAVALENTE, PARA REMOVER ARSêNICO TRIVALENTE DE UMA SOLUçãO AQUOSA, E, MEIO INSOLúVEL EM áGUA". Processo para a separação de arsênico pentavalente de uma solução aquosa usando meio de adsorção contendo N-alquil piridínio é descrito. Um meio oxidante e processo para a oxidação de arsênico trivalente em arsênico pentavalente com remoção de arsênico pentavalente assim formado é também descrito.
