Infrared spectroscopy confirmed the chemical modification of the titania matrix. The number of 2-aminothiazole groups attached to the titania was determined by Kjeldahl's method. The photocatalytic experiments were carried out in a cylindrical photoreactor thermostatted at 298 K. The resulting modified photocatalyst 2-aminothiazole titania (TiAT) revealed an enhance in the Hg (II) photoreduction capacity at studied pH values (3, 7 and 9). In addition, sorption studies showed that the photocatalyst TiAT presented a lower equilibrium time and a higher sorption capacity of Hg(II) ion, demonstrating that sorption plays a fundamental role in the photoreduction mechanism. ©2006 Sociedade Brasileira de Química.453-457eng2-aminothiazole3- chloropropyltrimethoxysilanePhotocatalysisTiO2Artigo10.1590/S0103-50532006000300004S0103-50532006000300004WOS:000237738400004Acesso aberto2-s2.0-337447333602-s2.0-33744733360.pdf69814486374563910000-0003-4179-0574
