      Machado, Fernando Machado; Ayyappan, Sophia Carmalin; Lima, Éder Cláudio; Dias, Silvio Luis Pereira; Prola, Liziê Daniela Tentler; Saucier, Caroline; Jauris, Iuri Medeiros; Silva, Ivana Zanella da; Fagan, Solange Binoto (2016) [Artigo de periódico]
      This study evaluated the feasibility of removing Alizarin Red S dye (ARS) from aqueous solutions, using nanoadsorbents such as single and multiwalled carbon nanotubes (SWCNT and MWCNT, respectively). The effect of pH, ...
    • Adsorption of a textile dye from aqueous solutions by carbon nanotubes 

      Machado, Fernando Machado; Bergmann, Carlos Perez; Lima, Éder Cláudio; Adebayo, Matthew Ayorinde; Fagan, Solange Binoto (2014) [Artigo de periódico]
      Multi-walled and single-walled carbon nanotubes were used as adsorbents for the removal of Reactive Blue 4 textile dye from aqueous solutions. The adsorbents were characterised using Raman spectroscopy, N2 adsorption/desorption ...
    • Application of carbon composite adsorbents prepared from coffee waste and clay for the removal of reactive dyes from aqueous solutions 

      Santos, Davis Castro dos; Adebayo, Matthew Ayorinde; Lima, Éder Cláudio; Pereira, Simone de Fátima Pinheiro; Cataluña Veses, Renato; Saucier, Caroline; Thue, Pascal Silas; Machado, Fernando Machado (2015) [Artigo de periódico]
      A novel carbon composite was prepared from a mixture of coffee waste and clay with inorganic:organic ratio of 1.3 (CC-1.3). The mixture was pyrolysed at 700 °C. Considering the application of this adsorbent for removal of ...
