“…In recent years, great hopes have been fostered in the application of waste materials from the agri-food industry as unconventional sorbents [ 12 ]. The largest group of sorption materials tested so far was lignocellulosic plant biomass [ 13 , 14 ], including stems [ 15 ] and leaves of crops [ 16 , 17 ], seed hulls [ 18 , 19 ], nut shells [ 20 , 21 ], as well as fruit [ 22 , 23 ] and vegetable peels [ 24 , 25 ]. Ample studies have also been carried out on the removal of dyes using waste from the wood industry, such as sawdust [ 26 , 27 ], bark [ 28 , 29 ], cones [ 30 , 31 ], or tree leaves [ 32 , 33 ].…”

This study examined the possibility of using various types of waste paper—used newsprint (NP), used lightweight coated paper (LWC), used office paper (OP), and used corrugated cardboard (CC)—for the removal of anionic dyes, Acid Red 18 (AR18) and Acid Yellow 23 (AY23), and cationic dyes, Basic Violet 10 (BV10) and Basic Red 46 (BR46), from aqueous solutions. The scope of this research included the characterization of sorbents (FTIR, SEM, BET surface area, porosity, pHPZC, effectiveness of water coloration), determination of pH effect on the effectiveness of dye sorption, sorption kinetics (pseudo-first-order model, second-order model, intraparticular diffusion model), and the maximum sorption capacity (Langmuir models and Freundlich model) of the tested sorbents. The use of waste paper materials as sorbents was found to not pose any severe risk of aquatic environment contamination. AR18, AY23, and BV10 sorption intensities were the highest at pH 2, and that of RB46 at pH 6. The waste paper sorbents proved particularly effective in removing cationic dyes, like in the case of, e.g., NP, which had a sorption capacity that reached 38.87 mg/g and 90.82 mg/g towards BV10 and BR46, respectively, and were comparable with that of selected activated carbons (literature data).
