Abstract

MéTODO PARA A REMOçãO DE MATERIAIS EM PARTìCULAS DE SUBMICRON A PARTIR DE áGUA CLORADA PELA ADIçãO SEQüENCIAL DE UM POLìMERO CATIÈNICO SEGUIDO PELA ADIçãO DE UM POLIMERO ANIÈNICO. Um método para remover materiais em partículas coloidais, de submicron, como hidrocarbonetos, a partir da água. O método incluí adicionar primeiramente um polímero catiónico solúvel como quitosana, um sal, ou solução de quitosana à água contendo os materiais em partículas de submicron e um agente de halogenação, seguida por adição de um polímero aniânico, solúvel ou sal aniónico à água. Os flocos resultantes são filtrados para remover os materiais em partículas de submicron.
