Abstract

Multiferroic Co substituted BiFeO₃ (BiFe_0.95Co _0.05O₃) compound was synthesized by complex sol-gel method and its potential application as an efficient magnetic adsorbent in sorption removal of organic contaminants (like Rhodamine B as a model compound) was investigated. The XRD, Raman, and PPMS measurement revealed that Co substituted BiFeO₃ enhances magnetic properties dramatically at room temperature without inducing any impurity phase. This aspect is very useful for many applications of Co substituted BiFeO₃ especially in magnetic separation of this catalyst after its utilization in water purification. The adsorption kinetics, isotherm, thermodynamic as well as the possible sorption mechanism was studied through batch experiments. Almost no negative effect on the sorption performance (i.e. the sorption rate and saturated sorption capacity) was found after substitution of Co in BiFeO₃. In addition, this substitution give rise to much higher coercive force of BiFe _0.95Co_0.05O₃ which can be recycled more easily by magnetic separation technology.
