摘要
Magnetic carboxyl-coated silica iron oxide nanoparticles (Fe3O4@SiO2-COOH NPs) were successfully synthesized, characterized, and then applied as a nano-adsorbent for removal of malachite green (MG) from aqueous solutions. According to the experimental results, about 97.5% of MG could be removed from aqueous solutions using an adsorbent amount of 0.5 g/L at pH=9 in 120min. The kinetics and equilibrium adsorptions is well-described by the pseudo-second-order kinetics and Langmuir model with the maximum absorption capacity of 263.16mg/g, respectively. Thermodynamic studies showed that the adsorption of the hazardous MG dye was spontaneous and endothermic with a random process.
