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.

“…Polyaniline also increases the interactions (hydrogen bonding and π–π attraction) between dye molecules and the membrane's surface to enhance the adsorption mechanism. [ 47 ] Figure 6b shows the effect of adsorption efficiency of methyl orange with change in concentration (0.5−4 g L −1 ) of the developed membrane (3P) for the same interval of time (3 h). Results show that adsorption efficiency gradually increases the concentration of 3P membranes (adsorbent) due to the increased number of active sites for dye molecules’ adsorption on the membrane surface.…”

Hybrid PVDF/PANI Membrane for Removal of Dyes from Textile Wastewater

et al. 2021

View full text Add to dashboard Cite

Treatment of textile wastewater has been a matter of considerable interest because of the potential toxicity, colloidal stability, and deformable nature of dyes. Herein, a novel polyaniline (PANI)/polyvinylidene fluoride (PVDF) hybrid membrane is developed to remove textile wastewater dyes. The hybrid membrane's contact angle decreases by increasing the concentration of polyaniline in the PVDF matrix, enhancing the hybrid membrane's hydrophilicity. Membrane properties, including porosity, antifouling property, solvent content, and pure water flux, are improved in the hybrid membrane compared with neat PVDF membranes. The purified water flux is enhanced from 28 to 47 L m−2 h, which indicates the impact of PANI on the hydrophilicity of the hybrid membranes. Among the hybrid membranes, 3P exhibits 85% dye rejection at 0.1 MPa operating pressure. Hence, the incorporation of PANI in the PVDF matrix is proposed to enhance the hybrid membrane's dye rejection and antifouling properties.

Fungicide Fluopyram (FLP) containing benzamides class has been scrutinized for the first time for its ecotoxicity and environmental lithosphere stationed fate from various climatic zones. Fate-decisive research inclusive of examining FLP's response in perspective of alteration via adsorption/desorption and disintegration in hydrolytic, photolytic, and bio-degradative procedures. Sorptive interactions determination was done by the batch equilibration approach and indicated its dependency on the chemico-physical properties of the soils. Fragile adsorptive interactions between soils and FLP molecules were established, as indicated by physio-sorption and a fragile exothermic response indicated by negative Gibbs free energy values (-8 to -15.3 kJ mol-1). The soil with the maximal adsorption, Kd(ads) =8.6 µg mL−1, was procured to have a significant organic matter content (1.30 %), resulting in a C-type isotherm that was scrutinized using a linear and Freundlich model. The analytical techniques, inclusive of ultraviolet-visible spectrophotometric and high-performance liquid chromatography procedures have been endeavored to examine FLP fate elucidation. Hydrolysis, photolysis, and biodegradation tests procured minimum halflives of 7.45, 1.29, and 5.77 days while the most remarkable were 10.6, 7.96, and 10.6 days, respectively. The results demonstrated that FLP displayed medium binding and thus low persistence in the tested soils while being extremely susceptible to transformative mechanisms. Current research can be embraced to include further augmentation of these degradative ways and to develop realistic methods for environmental cleanup through natural routes.
