Resumen:
It is known that the benefits offered by mesoporous silica (SiO2) such as being stable, innocuous, with high surface area and pore size, etc., make it attractive in a wide variety of technological, scientific, and medical applications. In addition, the surface of this solid can be modified / functionalized with different chemical substances, expanding its use and improving its selectivity. In the case of its application as adsorbent in water, our group has been working for a decade with mesoporous SiO2 in order to evaluate under what conditions and with what species these materials result effective. This work presents a study of the adsorption capacity of mesoporous SiO2 in water, with and without organic and inorganic linkers, towards cationic (paraquat PQ2+ and malachite green MG), polar / zwitterionic (norfloxacin NFX, doxycycline DXC), and anionic (methyl orange MO and 2,4-D) species in order to compare their performance, with that of the other adsorbents reported in literature. Finally, regeneration of the adsorbent and reuse (crucial parameter to be evaluated from the technology point of view) studies were also carried out and are discussed. Observaciones: Este congreso es de alcance internacional y nuclea a físico, fisicoquímicos, químicos inorgánicos y químicos ambientales de diferentes paises, por lo que es un evento afín a la especialidad o a linea de investigación llevada a cabo. La participación del Dr. Brigante en el evento es protagónica ya que se encuentra como supervisor del grupo de investigación.
