The aim of this study was to produce activated carbon (AC) from lignin obtained with deep eutectic solvents (DESs) of choline chloride–lactic acid. For this, lignin particles were produced using the DES. The DES lignin (DES‐Lig) was modified with zinc dichloride, and the lignin activated carbon (lig‐AC) was produced by carbonization at 600 and 900 °C. In this study, the AC obtained from the commercial...
