Preparation of magnetically separable Fe3O4 @ SiO2@ FeOOH nanoparticles for effective removal of Cr (VI) from aqueous solution

Abstract

In this study, Fe 3 O 4 @SiO 2 @FeOOH has been prepared and used as an adsorbent to eradicate Cr(VI) from aqueous media. Fe 3 O 4 @SiO 2 @FeOOH has been characterized by various characterization methods. Various factors on chromium adsorption such as the effect of pH, temperature, adsorbent dose, Cr(VI) concentration
