Has anyone tried this? I seen this article that suggests it makes it work again.
"The regeneration efficiency of activated carbons reaches 98 % even after 10 times of regeneration cycles."
It might even be better if the goal is color removal since absorbed metals done get removed from microwave radiation but organics seem to burn off.

Effect of microwave heating on the regeneration of modified activated carbons saturated with phenol - Applied Water Science
The purpose of this work was to investigate the effect of microwave irradiation on the regeneration of modified activated carbons (GAC/MW, GAC/Ni, and GAC/Cu). The untreated activated carbon (GAC pure) was used for blank experiment. Microwave heating was used for preparation and regeneration of...
