Batch and dynamic biosorption of basic dyes from binary solutions by alkaline-treated cypress cone chips
A simple alkaline pre-treatment of Cupressus sempervirens cone chips was performed to improve their biosorption capacity towards methylene blue and rhodamine B from aqueous solutions, in batch and continuous modes. Biosorption kinetics were determined from single and binary dyes solutions, and prope...
