Pine Sawdust-Based Activated Carbon for the Removal of Dyes from Aqueous Solutions
Short Introductive summary
A pine sawdust-based activated carbon was prepared by carbonization and activation with KOH and used for the removal of acid wood dyes form aqueous solutions. The carbon was thoroughly characterized and adsorption experiments of three acid dyes in batch and continuous mode were carried out. Batch studies were performed to analyze the influence of contact time, initial dye concentration, initial pH, and adsorbent dose. Regarding fixed-bed experiments, the breakthrough curves were determined by varying the flow rate, bed height, and initial dye concentration, and modeled using the Yoon-Nelson and Thomas models. Regeneration experiments were conducted using H2O2 as desorption agent. This study showed that the activated carbon prepared from pine sawdust has a high potential to remove anionic dyes.
