Batch Adsorption of Maxilon Red GRL from Aqueous Solution by Natural Sugarcane Stalks Powder

Abstract

Sugarcane stalks powder was tested for its efficiency of removing a textile dye Maxilon Red GRL from aqueous solution. Different parameters affecting dye removal efficiency were studied. These parameters include contact time, initial dye concentration, adsorbent dose, ionic strength, pH, and temperature. Langmuir and Freundlich isotherm models were applied to the equilibrium data. The data fitted well with the Langmuir isotherm (). The maximum monolayer adsorption capacity () was found to be 20.96 mg/g at an initial pH of 7.2. The temperature variation study showed that dye adsorption is exothermic and spontaneous with increased randomness at the solid solution interface. The results indicated that sugarcane stalks could be an alternative for more costly adsorbents used for dye removal. The kinetic of the adsorption process followed the pseudo second-order kinetics model.

“…DMT is an industrial dye and has been used as a represented compound of azo dyes worldwide for many years. These kinds of dyes are described as among the azo dyes which must be taken into consideration in terms of living organisms for industrial fields [3,4]. When we compare azo dyes with other dyes, they have many advantages such as low cost, simple and short synthesis process etc.…”

“…Fig. 3 shows the effect of adsorbent dosage as investigated by El-Sayed et al, 2013, where the adsorption on Maxilon red by sugarcane stalk powder was found to increase from 11.25 to 95.10 %. The increase in adsorption recorded within the dose range of 1.0-4.0 g/L could be attributable to the sugarcane stalk powder's increased surface area and the availability of adsorption sites.…”

“…Because of its ease of implementation, convenience, low cost, and non-toxicity of the adsorbents used, it is favoured over other wastewater treatment technologies . The following adsorbents have been used in the removal of Maxilon dyes from wastewater: clay (Chaari et al, 2019;Cheknane et al, 2010), sugarcane stalk powder (El-Sayed et al, 2013), walnut shell (Deniz, 2014), waste sludge (Sarioglu and Așkal, 2018), pine sawdust (S ¸entürk and Yıldız, 2020a; S ¸entürk and Yıldız, 2020b), amongst others.…”

Application of Fenton reagent and adsorption as advanced treatment processes for removal of Maxilon Red GRL

“…The initial pH of the aqueous solution plays an important role in the adsorption capacity (El-Sayed et al, 2013). The effect of initial pH on removal of MR GRL from aqueous solutions was investigated by varying the pH range of 2.0-10.0 at 30 °C temperature for 150 min contact time.…”

“…The fact that, compared to Freundlich isotherm, the Langmuir isotherm fits the experimental data due to the homogeneous distribution of active sites on the surface of adsorbent. The Langmuir model is based on the assumption that maximum adsorption corresponds to a saturated monolayer of solute molecules on the adsorbent surface (El-Sayed et al, 2013).…”
