A higher catalytic efficiency was obtained than the reported values for TiO<jats:sub>2 <\/jats:sub>under the same conditions. Chrysotile, a clay mineral fibre of low cost and relatively abundant, probably acts as a catalyst through an Advanced Oxidative Process (AOP) involving free radical formation. In this work, experiments with non\u2010ionic \u2013 Triton X\u201045 (octil\u2010phenoxy polyethoxy ethanol) \u2013 and cationic \u2013 Herquat 3500 (alkyl dimethyl benzyl ammonium chloride) \u2013 surfactants were carried out. Diluted aqueous solutions (50 ppm) of these surfactants were kept in contact with chrysotile (4.0 g) in the dark at room temperature. The aromatic ring disappearance was followed through the absorbance peaks at 224 nm (Triton X\u201045) and 208 nm (Herquat 3500) in the UV spectra. After 4 h, reductions in the surfactant solution concentration of 65.0% and 35.0% were observed for the Triton X\u201045 and the Herquat 3500 surfactants, respectively. In both cases, reactions carried out without aeration showed a lower reduction of the aromatic ring concentration (30.0% less) when compared to the values obtained for the systems with airflow. The system containing the non\u2010ionic surfactant seems to achieve equilibrium after 2 h, what is not observed for the cationic surfactant system.<\/jats:p>","DOI":"10.1002\/clen.200600002","type":"journal-article","created":{"date-parts":[[2007,2,8]],"date-time":"2007-02-08T14:43:21Z","timestamp":1170945801000},"page":"100-103","update-policy":"http:\/\/dx.doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Use of Chrysotile Fibres in the Degradation of Cationic and Nonionic Surfactants in Aqueous Solutions"],"prefix":"10.1002","volume":"35","author":[{"given":"Adriano","family":"Fachini","sequence":"first","affiliation":[]},{"given":"In\u00e9s","family":"Joekes","sequence":"additional","affiliation":[]}],"member":"311","published-online":{"date-parts":[[2007,2,8]]},"reference":[{"key":"e_1_2_1_2_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0043-1354(02)00444-X"},{"key":"e_1_2_1_3_2","first-page":"81","author":"Perkowski J.","year":"2005","journal-title":"Fibres Text.
