Abstract

Modification of algae–silica (AS) hybrid material from Tetraselmis sp. biomass (AS) was performed through a sol–gel simultaneous process and coated with Fe3O4 magnetite nanoparticles (MNPs). Algae–silica hybrid material from Tetraselmis sp. biomass-coated MNPs (AS-MNPs) were used as adsorbents of heavy metal ions. The adsorption processes of Ni(II), Cu(II), and Zn(II) ions with AS and algae-silica-magnetite nanoparticles (AS-MNPs) fit pseudo-second-order kinetic models. The rate constant and adsorption capacity of Ni(II), Cu(II), and Zn(II) ions for AS-MNPs obtained from these experiments were higher than those of AS. AS-MNPs material is an effective adsorbent and can be used to absorb heavy metal ions in solution.
