This paper aims to investigate the uses of leonardite powder (LP) as an effective adsorbent for the removal of basic red 18 (BR18) and reactive red 180 (RR180) dyes. LP was characterized using scanning electron microscopy (SEM), energy-dispersive X-ray spectroscopy (EDX), Zeta potential, Brunauer-Emmett-Teller (BET) analysis, Fourier transform infrared spectroscopy (FTIR), and X-ray fluorescence (XRF). The adsorption process was assessed based on pH, size and the amount of the adsorbent, BR18 and RR180 concentration, and the contact time. BR18 dye was completely adsorbed onto the LP (the removal efficiency equals 100%) after 45 min at the optimum condition (original pH [6.5], the particle size of 45 μm, the adsorbent dose of 0.25 g/L, and the initial concentration of 10 mg/L). For RR180, the maximum removal efficiency (74%) was obtained when 1 g/L LP with 45 um size was added to an RR180 solution of 10 mg/L concentration. Temkin isotherm was used to explain the adsorption of BR18. In contrast, RR180 adsorption was described by the Freundlich model. The adsorptions of both dyes followed the pseudosecond-order kinetics. The reusability of the LP was assessed. For BR18, the efficiency decreased to 96% in the second cycle and reached 42% in the fifth cycle. In RR180, LP was not able to be reused efficiently. As a result, the LP ability for BR18 removal is higher than the RR180 in terms of uptake and reusability. Practitioner Points• BR18 and RR180 dyes elimination was carried out with leonardite powder (LP).• The maximum removal efficiencies for BR18 and RR180 were 100% and 74%, respectively.• The LP ability for BR18 removal is higher than the RR180 in terms of uptake and reusability.

“…Despite this, the calculated value (q e ) for the pseudo-second-order model deviated significantly less from the pseudo-first-order experimental data. The fact that the pseudo-second-order model has a higher R 2 value indicates that this model equation is more effective for adsorption kinetic studies (Yagnamurthy et al 2022, Isik et al 2022.…”

Today, various methods are used to remove the dye pollution in the increasing water. Adsorption is a fast and effective method that has been used since the past. The value of the obtained adsorption capacity varies according to the type of biosorbent material used. The seeds of the fruit of Sophora Japonica (SJfs), a tree commonly found in nature, were pyrolyzed at 450°C to produce biochar (SJfsB) in this study. Iron nanoparticles were immobilized into the SJfsB structure to form a more active biosorbent matrix. The obtained SJfsB and nM-SJfsB were used in the removal of methyl blue, an anionic dye. SJfsB and nM-SJfsB used for dye removal were characterized by FT-IR and SEM instruments. The obtained results revealed that the adsorption process occurred in the pseudo-second-order and was consistent with the Langmuir model. The maximum adsorption capacity for MB removal was 434.783 mg/g for nM-SJfsB and 76.923 mg/g for SJfsB, respectively.

“…Recently, various techniques, including using a green biochar/iron oxide composite, 7 coated membranes, 8 surfactant-modified biomass, 9 coagulation, 10 modified magnetic nanosorbents, 11,12 hydrochar adsorption, 13,14 and photocatalytic degradation, 15,16 have been applied to remove both cationic and anionic dyes from water. Among these methods, semiconductor-based photocatalysis is thought to be the most promising method because it can convert a broad range of organic contaminants into less toxic compounds, including CO 2 , and H 2 O, without the use of expensive oxidants.…”
