“…To understand the adsorption process, the study of various factors effecting the adsorbent/solution interface needs to be evaluated. One of the major factor that influences the adsorption phenomenon is solution pH as it affects the adsorbent surface charge, ionization state, and solubility of dye [17,32]. Therefore, we carried out the adsorption of MG on the AC@PIN composite as a function of pH ranging from 2 to 10 at 20 • C. The dye initial concentration was 50 mg L −1 .…”

The present study is aimed at the synthesis and exploring the efficiency of a novel activated carbon incorporated polyindole (AC@PIN) composite for adsorptive removal of Malachite Green (MG) dye from aqueous solution. An AC@PIN hybrid material was prepared by in situ chemical oxidative polymerization. The physico-chemical characteristics of the AC@PIN composite were assessed using Fourier-transform infrared spectrometer, X-ray diffraction, scanning electron microscopy, energy dispersive X-ray spectroscopy, ultraviolet visible spectroscopy, and determination of point of zero charge (pHPZC). A series of adsorption studies was conducted to evaluate the influence of operational parameters such as pH, contact time, initial dye concentration, AC@PIN dosage, and temperature on dye adsorption behavior of developed composite. A maximum dye removal percentage (97.3%) was achieved at the pH = 10, AC@PIN dosage = 6.0 mg, initial dye concentration 150 mg L−1, and temperature = 20 °C. The kinetic studies demonstrated that the adsorption of MG on AC@PIN followed pseudo-second-order model (R2 ≥ 0.99). Meanwhile, Langmuir isotherm model was founded to be the best isotherm model to describe the adsorption process. Finally, the recyclability test revealed that the composite exhibits good recycle efficiency and is stable after 5 cycles. The obtained results suggest that AC@PIN composite could be a potential candidate for the removal of MG from wastewater.

In this work, hydroxypropyl starch sulfate (HPSS) and Aspergillus oryzae (Asp. oryzae) were successfully synthesized and investigated for aqueous methylene blue (MB) adsorption. The as-prepared adsorbents were also characterized extensively using FTIR, XRD, SEM, EDX, and BET surface area analyses to elucidate their functional, textural, and morphological properties. Also, the effects of initial dye concentration, contact time, and pH on the adsorption performance of both adsorbents were systematically investigated. Due to the significant surface area differences, the HPSS recorded a higher maximum adsorption capacity (qmax) of 52.41 mg/g at 20 mg/L initial concentration, 60 min, and pH 8.0, while the Asp. oryzae recorded a qmax of 37.26 mg/g at 20 mg/L initial concentration, 60 min, and pH 9.0. Specifically, the –SO3 groups on the HPSS shared some electrostatic affinity with the MB dye cationic center (N+ backbone), while a hydrogen bond is formed between the hydroxyl groups of the starch and N+ backbone of the MB dye. Also, the nitrogen- and oxygen-containing groups on the Asp. oryzae provided active sites for the binding of MB species. Also, the XRD spectra of the loaded HPSS showed a decrease in the sharp crystalline peaks, while no structural changes were observed in the case of loaded Asp. oryzae. Therefore, the effectiveness of the HPSS and Asp. oryzae for adsorbing MB was established in the study.
