Serial title, monograph or event: | Quimica Nova | Volume: | 31 | Issue: | 8 | Abstract: | In the present paper, the use of poly(styrene sulfonate) (PSS), produced from discarded polystyrene materials through heterogeneous and homogeneous processes, was investigated. The use of PSS for water treatment, using a kaolin suspension as wastewater model, reduced water turbidity for all the employed materials when compared to the blank analysis, without PSS. The most efficient polyelectrolyte was PSS cups obtained by homogeneous route. The same behavior was observed for real system. The homogeneous PSS cups showed a balance between a moderate molecular weight and high anionic character that improved flocks formation and water removal turbidity. | URI: | https://hdl.handle.net/10316/110860 | ISSN: | 0100-4042 | DOI: | 10.1590/S0100-40422008000800017 | Rights: | openAccess |
