“…Figure 1(b) shows distinct significant peaks at various wavenumbers: 1,032, 1,612, and 3,514 1/cm. The vibration mode of the strong hydrogenbonded O-H stretching of the alcohol is seen at 3,514 1/cm, similar spectra has been reported by Venkatesh and Arutchelvan (2020). As adsorption process takes place at the surface of an adsorbent, its very sensitive to surface features, such as the pore size distribution.…”

“…As shown in Figure 3(c) RBD removal has achieved of 99.04% at 50 mg/L solution. Additionally, it was noted that the original dye concentration increases the rate of RBD removal from an aqueous solution got reduced (Venkatesh and Arutchelvan, 2020). Figure 3(d) shows the study of pH optimization for dye removal.…”

“…This is caused by the early presence of highly active sites and the destabilization of the driving force. As the duration rises, the dye's ability to bind to the active sites becomes less and less until it reaches the equilibrium (Venkatesh and Arutchelvan, 2020;Sun et al, 2013). The removal of RBD varies dosages of suspended CIBs is shown in Figure 3(b).The amount of the adsorbent used has a significant impact on the method used to calculate an adsorbent capacity for a certain amount of adsorbent.…”

“…Adsorption isotherms, often expressed as the ratio of the amount adsorbed to the amount still in solution, describe the equilibrium connection between an adsorbent and an adsorbate at a specific temperature. Two different models were used to examine the equilibrium adsorption isotherm, namely Langmuir and Freundlich which often called the two-parameter adsorption isotherms (Venkatesh and Arutchelvan, 2020). The correlation coefficient (R 2 ), extreme monolayer ability of adsorption (qm), and error values like SSE and RMSE were assessed using the ORIGINPRO 9.0 software utilizing the experimental data and non-linear equation (Table 1).…”

The present research employed immobilized Canna indica beads (CIBs) to obtain maximum degradation of highly toxic Reactive Blue Dye (RBD), predominantly used in textile industry. The CIBs were characterized using FTIR and SEM-EDX analysis. A batch adsorption study was conducted to measure the removal of harmful RBD dye. Different factors were examined in the biosorption technique to achieve the maximum level of toxic dye elimination, such as adsorbent-solute interaction time (5-120 min), solution pH (2-10), adsorbent dose (25 to 250 mg/100 mL), RBD concentration (50-250 mg/L), and temperature (30-60°C). Removal of 99.96% of RBD was successfully achieved at the optimum pH 7, RBD concentration of 50 mg/L, adsorbent dosage of 150 mg/100 mL, a temperature of 303 K, and 60 min of interaction time. The Langmuir isotherm and pseudo-second-order (PSO) kinetic model data have been found to be an ideal match compared to the Freundlich isotherm and pseudo-first-order (PFO) kinetic model. The maximum adsorption capacity onto CIBs biosorbent was found to be 70.49 mg/g. It was noticed that the chemical reaction occurred naturally and released heat during the process which denoted an exothermic reaction. These results shown that the adsorption of RBD removal is efficient using prepared adsorbent from Canna indica root tubers. Therefore, these CIBs could be used for other toxic dyes and heavy metals from industrial wastewater.

The present work evaluates the synthesis of a novel, inexpensive, and environmentally friendly chemically-treated avocado seed powder (CTASP) as an adsorbent in removing alizarin red S (ARS) from synthetic solution. By using a set of analytical techniques, including FTIR, XRD, EDX, RS, and SEM, the adsorbent was characterized for its physical and chemical properties. Batch study experiments were conducted to determine the effectiveness of the CTASP as an adsorbent. The maximum adsorption capacity of 67.08 mgg-1 was attained at optimum conditions of 3 gL-1 adsorbent dosage, pH 3, contact time of 30 min, and at temperature 303 K. After 30 minutes, the equilibrium was reached, and the experimental data was explained for isotherm, kinetic, and thermodynamic processes. The results indicated that pseudo-second-order kinetics and the Freundlich isotherm were the best fits for the data. The findings of the analysis of the thermodynamic parameters for the process showed that the system was an exothermic and spontaneous. According to the desorption studies, 0.1 M NaOH can be utilized as a separating reagent to desorb 90.53% of ARS that was adsorbed. Regeneration experiments were conducted to make the process more practical and affordable, and it was discovered that the CTASP adsorbent could be successfully regenerated up to four times. In comparison with other adsorbents, the current low-cost adsorbent had the exceptional regenerative capability and delivered multilayer adsorption capacity. Additionally, it has been demonstrated that the CTASP is an effective material for the detoxification of ARS dye from wastewater.
