Abstract: Three-dimensional (3D) hierarchical magnetic hollow sphere-like CuFe2O4 (3D HMHS-CuFe2O4) were designed to sensitively detect four Sudan dyes combined with HPLC-DAD. The formation mechanism of 3D HMHS-CuFe2O4 is also discussed. Compared to the particle-like CuFe2O4 (PL-CuFe2O4),… read more here.
