Elemental analysis and thermal analysis (TGA and DTGA) are carried out on the BLs, while the surface area (S BET), micro-/mesoporous distribution, adsorption capacity of methylene blue (MB) and iodine (I2-value), as well as Fourier transform infrared spectra (FT-IR) and scanning electron micrograph (SEM) are studied on synthesizing ACs.
