Use of aqueous two-phase PEG-salt systems for the removal of anionic surfactant...
Murari, Gabriella Frade; Penido, Jussara Alves; Silva, Heriveltom Morais da; Baeta, Bruno Eduardo Lobo; Aquino, Sergio Francisco deLinear alkylbenzene sulfonates (LAS) are synthetic anionic surfactants that are extensively used in many industries. As a result, large volumes of effluents containing high levels of these compounds are discharged into water bodies, causing risks to aquatic flora and fauna. Then, there is a need for environmentally safe and economically viable technologies for the removal of LAS from aqueous matrices. The prese...

Partition study of textile dye remazol yellow gold RNL in aqueous two-phase sys...
Alvarenga, Juliana Maria de; Fideles, Renata Aparecida; Silva, Maira Vieira da; Murari, Gabriella Frade; Taylor, Jason Guy; Lemos, Leandro Rodrigues deThe removal of organic dye pollutants from wastewater produced by the textile industry is a complex problem that presents potential health risks to the general public. Remazol Yellow Gold RNL (YR) dye is readily used to dye cellulose base materials and the methods developed for its removal from aqueous systems are either inefficient or too expensive to be adopted by smaller textile manufactures. Our approach is...
