Because of their ubiquitous industrial usage, dyes are significant water pollutants. Adsorption is an effective method for eliminating colors from tainted water. In the twenty‐first century, industrialization is growing at a dizzying rate. During this stage, more noble colors and dyes are used. These hues contribute to a wide range of contaminants, including water, soil, and air pollution. The objective of this report is just to discuss the chemical and bio‐based adsorbents used to remove various types of industrial dyes. Several adsorption isotherm assumptions and mathematical formulations were investigated. The effect of a variety of factors on adsorption phenomena is addressed.

“…MB is a heterocyclic cationic synthetic organic dye that can make water unsafe to drink. The molecular weight of MB is 319.85 g mol − 1, and with a molecular formula of C 16 H 18 N 3 ClS, MB has good solubility in water and can stay stable for a long with water at a normal temperature [29]. It is a dangerous substance due to its toxic, carcinogenic, and non-biodegradable potential [30].…”

In this study, the adsorption of cationic organic dye methylene blue (MB) from an aqueous solution was investigated using a nano-adsorbent (active carbon) made from the dead bark of Azadirachta indica (neem) by using FTIR, zeta-potential analysis, X-ray diffraction, ultraviolet-visible spectroscopy, FESEM, BET, and TEM analytical tools, the synthesized nano adsorbent was evaluated for its characteristics. N2 sorption study confirms that the prepared adsorbent depicted a type IV isotherm with H3 type of hysteresis loop, which reveals the subsistence of the development of mesoporous material with a pore diameter in the 2–50 nm range. In the batch approach, the experimentations were run to equilibrium isotherm study. For the removal of the dye, the effects of variables, including contact time, pH, temperature, initial dye concentration, and adsorption dose, were investigated. In 80 min. of equilibrium time, 99.49% of MB dye at 30 mg/L of initial concentration was withdrawn at pH 11 with 30 mg of adsorbent. However, the % removal of dye was found to be declined to 90.62% on a rising initial concentration of 60 mg/L under similar conditions. The adsorption data was found to be appropriate to the Langmuir isotherm model, as confirmed by the correlation coefficient (R2) value (0.997), and the utmost adsorption competence was estimated to be 106.92 mg/g at 303 K. In addition, it was found that the removal process followed a pseudo-second-order kinetics and intra-particle diffusion of MB dye molecules process is the controlling process but not a sole directing factor. The negative ΔG° and positive ΔH° decided the spontaneity and endothermic nature of adsorption practice, while the positive value entropy (ΔS°) reflected that adsorption of MB molecules favored an increment of disorderliness at the adsorbate-adsorbent interface.

“…Among all other methods of dye treatment, adsorption is most advantageous because of its higher efficiency, low operating cost, and consumption of less energy, low toxicity, greater surface area, faster Removal with easy chemically surface modification, easy maintenance, and simplicity. Also, an easy separation can be considered as a suitable method for the wastewater purification process (Hassan, 2021; Kumar & Acharya, 2013; Kumar & Kumar, 2015; Muhammad et al., 2021; Singh et al., 2010; Shakoor and Nasar, 2016; Shubhada et al., 2021).…”

A fixed‐bed column study was studied to assess the performance of sodium bicarbonate modified Bambusa Tulda to remove Safranin from wastewater. Fourier Transform Infrared Spectroscopy analysis shows the existence of carboxyl as well as hydroxyl bonding and grouping. Scanning Electron Microscope analysis shows the enhanced structure of Bambusa Tulda before and after chemical modification, and Energy dispersive X‐ray analysis shows the existence of Na, O after chemical modification with sodium bicarbonate. The maximum removal was found at higher bed depth and low flow rate. The breakthrough analysis time and exhaust time increase with an increase in bed height. At 5 ml/min flow rate, with initial concentration of 50 mg/L and bed height of 15 cm of adsorbent, shows best removal rate of safranin dye in column analysis. The Bed Depth Service Time (BDST) model and Thomas model analysis remained similar with experiment results, which indicates that they are suitable for the design of column study. It is being concluded that sodium bicarbonate modified Bambusa Tulda is an effective, low cost and readily available adsorbent for the adsorption of Safranin from wastewater.
