Nanostructured MnO2 catalyst in E. crassipes (water hyacinth) for indigo carmine degradation

The use of water hyacinth’s dried matter (Eichhornia crasippes) as a support matrix for nano-MnO2 and its application for the removal of indigo carmine (IC) was studied. Different pretreatment processes were tested and results indicated that an acid-alkali pretreatment is an efficient method to bind...
