Study of dye adsorbtion from water on silica materials using an optical fiber sensor

Resumo

The adsorption process on aqueous phase can be described as the exchange between a solvent molecule eletrostatically attracted to a solid surface and the molecule of a given solute. In this research the capability of three different silica materials in removing a dye from water was evaluated using an optical fiber sensor. Despite the better results, the nanomaterials data showed higher dispersion due to the presence of dynamic light scattering on particles which got stably suspended, and crystalline quartz showed the lowest manufacturing cost.
