Does anyone have any tricks for KMnO4 work up. The MnO2 produced is pretty gross to filter. Filter aid works relatively well, but are there any chemical methods to reduce or dissolve the MnO2.
The older literature treats the reaction with SO2, but that is pretty gross. I have read in another post that sulfuric acid followed by H2O2 is a possibility. Also, sulfuric and NaCl. Does anyone have any experience with this?
Any tricks or ideas are greatly appreciated!
