“…The evaluation of the potential suitability of used natural carbon materials as low-cost and alternative sorbents should also include a comparison of their adsorption capacity with other materials reported in the literature. The adsorption of Direct Orange 26 dye was studied on various materials including sawdust (Izadyar and Rahimi 2007, Kuśmierek et al 2020a, Kaushik et al 2009, rice straw (Tomczak and Tosik 2014), sugarcane bagasse pith (Kaushik et al 2009), corn cobs (Tomczak and Blus 2016), raw and modified rice husks , Bhatti et al 2020, brick powder (Kaushik et al 2009), magnetic Fe@graphite core-shell nanocomposite (Konicki et al 2017), halloysites (Kuśmierek et al 2020b), polyelectrolytes (poly(2-vinylpyridine) and poly(4-vinylpyridine)) and their composites with carbon (CarTunaF2VP and CarTunaF4VP) (Herrera-González et al 2021) as well as copper nanoparticles synthesized from Tilapia fish scales (Rafique et al, 2022). A comparison of the adsorption capacity of the different sorbents toward DO26 is shown in Table 4.…”

Wastewater dyes from the textile, paper, tanning, distillery, food industries and the production of dyes itself pose a significant threat to the environment. Despite the huge production volume, exact data on the number of dyes released into the environment are not available. It is estimated that about 10-15% of the dyes used end up in the environment along with sewage. At the same time, it is known that these substances are highly toxic, mutagenic, and low biodegradable (Wani et al. 2020). They are extremely harmful to living organisms, they can cause allergies, and skin sensitization, which often leads to neoplastic diseases. When discharged into water, they negatively affect the processes of photosynthesis, disrupt the transmission of light, and disturb the biocenosis in the ecosystem (Lellis et al. 2019).Because of the significant threat posed by dyes to the aquatic environment, an extremely important problem is the effective and efficient treatment of wastewater containing these pollutants. Due to the complex chemical structure and physical and chemical properties of substances used as dyes, the selection of an effective method of their removal is a complex and difficult problem, which is still the subject of numerous studies. Currently, the most commonly used methods are adsorption, coagulation, oxidation, and ultrafiltration. It should be noted that the use of chemical methods of removing dyes from wastewater is associated with the problem of the formation of intermediate products of decomposition of these substances (with equally toxic properties), as well as with the formation of significant amounts of sewage sludge. Therefore, an alternative and frequently used solution is adsorption. Due to the wide range of sorbents, selectivity, easy implementation of the process, low operating costs, and the lack of onerous sewage sludge formation, this method is increasingly used.A significant limitation of the use of this process is the high costs of obtaining and regenerating the most used sorbents, such as activated carbons or zeolites. For this reason, there is need and justified research on the search for new adsorbents with a satisfactory sorption capacity, preferably classified as low-cost sorbents, i.e., materials that do not require additional processing, are of natural origin, or are waste requiring disposal, are safe for the environment, and available in significant amounts (Gupta & Suhas 2009, Sočo et al. 2020). Among natural substances with the characteristics of sorbents that can be used as dye sorbents, peat, lignite, and hard coal are of significant importance (

Tamazert kaolin was modified with dimethyl sulfoxide (DMSO). The starting material and resulting from the intercalation were characterized by X-ray diffraction, Fourier transform infrared spectroscopy and scanning electron microscopy (SEM). Intercalation caused considerable changes in our clay by increasing the basal spacing to 11.22 Å, an intercalation rate of 98 %. The adsorption of methylene blue was studied as a function of pH, contact time, temperature, dye concentrations and adsorbents. Kinetic data have been adequately described by the pseudo-second order and intraparticle scattering model. The adsorption isotherm is in good agreement with the Redlich-Peterson model. A change in thermodynamic values (ΔH°, ΔS° and ΔG°) was observed after intercalation. Adsorption became non-spontaneous exothermic and ordered.

“…Many different purifying methods are used to treat this type of wastewater. Coagulation, chemical oxidation, electrochemical methods and sorption are applied to remove dyes from wastewater [1,[8][9][10][11][12][13][14][15][16][17][18][19][20][21][22][23][24]. The coagulation process, conducted with magnesium hydroxide enhanced by addition of kaolin, was used to remove two reactive dyes: reactive red (X-3B) and reactive yellow (X-R) [9].…”

Organic dyes are widely used in many industries (textiles, food, cosmetics, medicine and biology). These plants produce wastewater containing dyes. Even small amounts of dyes can cause a strong colour of wastewater. Therefore, it is very important to effectively remove residues of these pollutants from the wastewater, before discharging them into the environment. The sorption process is one of the methods used to remove dyes. However this method is often unprofitable economically in comparison with other dye removal processes, due to the high cost of commercial sorbents. Therefore, research is currently conducted in order to find waste materials that can be used as sorbents. The static sorption process of two dyes were carried out (Acid Red 18 and Acid Green 16) with the use of dried excess sludge. The activated sludge (excess) came from a municipal sewage treatment plant that purifies wastewater from carbon, nitrogen and phosphorus compounds. During the study the most favourable pH of the process and the contact time of the sorbent with the dyes were determined. It was observed that for both dyes the highest effectiveness of dye removal was obtained at pH = 2. The most favourable contact time was equal to 60 and 180 minutes for Acid Red 18 and Acid Green 16 respectively. In addition, in order to establish process parameters, a different models of sorption isotherm was examined. The studies showed that the sorption capacity (calculated based on Langmuir model) was much higher in the case of Acid Green 16 (qm = 434.8 mg/g) than for Acid Red 18 (qm = 109.9 mg/g). The experiments to evaluate the effect of pH, contact time on the process effectiveness and to determine the sorption isotherm were conducted at 293.15 K.
