Preparation and characterization of activated carbon from leather waste microwave-induced pyrophosphoric acid activation.

Highlights: [•] Leather waste was used as precursor. [•] H4P2O7 was used as the activation agent to make the structure of carbons. [•] Microwave technique was adopted to prepare activated carbon. [•] Maximum methylene blue capacity of 303.03mg/g was reported using Langmuir isotherm. [Copyright &y& Elsevier]
