In the present study, batch adsorption experiments were carried out to investigate the removal of methyl orange (MO) from aqueous solution using sugar scum powder as an effective inorganic adsorbent which is a cheap precursor and abundant. The characteristics of this material were determined using XRD, SEM/EDX, and FTIR. The adsorption performance of sugar scum powder was evaluated using MO as the model adsorbate. Effects of various parameters such as initial dye concentration, contact time, and adsorbent dose were studied. The adsorption process can be best described by the pseudo-second-order kinetic and Langmuir adsorption isotherm models. Maximum monolayer adsorption capacity for MO removal was found to be 15.24 mg/g at temperature 22°C and pH 7.2. Moreover, thermodynamic parameters suggested that the adsorption of MO onto sugar scum powder was a spontaneous and exothermic process. The results demonstrated that sugar scum is a suitable precursor for the preparation of efficient adsorbent for dye removal from wastewater.

“…Therefore, the removal of MB from wastewater using cost-effective adsorbents is a key environmental concern. For the removal of dyes, several techniques such as membrane filtration [12], biosorption [13], adsorption [14], and photocatalytic processes [15] are frequently used. Among the techniques mentioned, the adsorption method is considered as the most outstanding technique since it is the simplest, cheapest, and most successful technique for generating high-quality dye effluents.…”

Exploiting waste materials to make cost-effective adsorbents and waste management methods are gaining more attention. In the current study, rubber wastes derived from dipping tank coagulum (DTC) in the glove manufacturing industry were converted into a novel polymeric-adsorbent via a simple sulfonation reaction with concentrated sulphuric acid and was used for the adsorption of methylene blue (MB) dye from aqueous solutions commonly found in contaminated waters. FT-IR, EDX, FESEM, and BET techniques were used to characterize the rubber waste before and after modification. The highest MB removal efficiency of 99.03% was achieved in the condition of initial concentration, adsorbent dosage, pH, contact time, and temperature were 15 mg/L, 30 mg, pH 7, 300 min, and 25 °C, respectively. The adsorption of MB was analyzed using experimental data fitted in a monolayer isotherms model with a maximum adsorption capacity of 119 mg/g. The kinetic model was revealed to agree with the pseudo-second-order kinetic model. Furthermore, SRW retained 90.45% of the removal percentage after four cycles of the repeated adsorption-desorption process. Conclusively, these findings suggest that rubber waste could be a suitable low-cost adsorbent to remove organic dyes from polluted water.
