Sintesis manganese ferrite (mnfe2o4) dengan doping ion cu2+ menggunakan metod…

The synthesis of manganese ferrite doped with copper ions was carried out and applied as a cataliyst for degradation of methylene blue dye. The synthesis was conducted by reacting a solution of KMnO4 and FeSO4.7H2O in a 2:1 molar ratio using the sol-gel method, and calcined at different variations of 1 hours, 2 hours, 3 hours, and 4 hours at a constant temperature. .........................dst
