Recebido em 20/3/08; aceito em 23/10/08; publicado na web em 6/3/09 APPLICATION OF SYNTHETIC ZEOLITES AS BUILDER IN DETERGENT FORMULATION. The study consists is the application of zeolites NaX, NaY and A as builder in detergent formulations to eliminate the hardness of water. Therefore, the adsorption of ions Ca +2 and Mg +2 were evaluated, and the effect of the cleaning action of the surfactant sodium dodecil sulfate (SDS) through tests of detergency. The experiments were conducted in bath system (with shaking) and quantification of metals was performed by atomic absorption spectrometry. Zeolite A showed the best results for adsorption of Ca ++ and Mg ++ with retention rates of around 90 and 70% respectively and acted positively on the action of cleaning the surfactant SDS.

TiO2 nanoparticles dispersed in ordered mesoporous CMK-3 carbon with different Ti contents were successfully synthesized and their activity in the photocatalytic degradation of ibuprofen was presented. The photocatalysts were characterized...
