“…This dye effluent contains enormous salt and organic content and they are less biodegradable. Discharge of these dyes into natural water system without the treatment results in ecological imbalance [1][2][3][4]. Synthetic dyes are resistance to the physicochemical reaction and have thermal and optical stability due to the complex aromatic structure [5,6].…”

Biomass-derived adsorbents have been intensively studied due to their competence in reducing pollutants with conventional methods. Flowers are used as source in medicine, cosmetics and even as adsorbents for pollutant abatement. In this study, the microparticles from Chrysanthemum indicum were used as adsorbent for reducing the Congo red dye concentration from synthetic solution. Batch trials were evaluated to understand the influence of factors and optimization was carried out using central composite design. Maximum reduction (84.1%) achieved under the optimized settings of pH (1.0), adsorbent dose (300 ppm), stirring speed (150 rpm), and contact time (75 min) at initial dye concentration (150 ppm at 30 °C). Microparticle size ensured with surface morphology of the adsorbent using electron microscopy and functional groups was studied using infrared spectroscopy techniques, respectively. Regression coefficient (R 2) value was obtained as 0.956 which indicates that the predicted values were in good agreement with their corresponding experimental values for the Congo red dye adsorption. Based on the investigation, it is inferred that the Chrysanthemum indicum flower has the potential for Congo red dye reduction from aqueous solution.

“…Dyes are used in many industries such as textile, paper, plastics, cosmetics, leather etc., among them congo red (CR) is the most used one [3]. It is a benzidine based ionic diazo carcinogenic dye which is mostly used in cotton textiles, paper and plastic industries [4][5][6]. It is difficult to biodegrade because of its complex aromatic structures.…”

“…Commercially, electrochemical coagulation [10], photocatalytic degradation [11], ozonation [12], electrochemical oxidation [13], nano filtration [14], reverse osmosis [15], adsorption [16] methods, etc are used to remove the toxic dyes from industrial wastes. Among these, adsorption method is the most effective one since it is fast, inexpensive and sludge free method to remove the organic dyes [5,17].…”

CeO2–TiO2 nanocomposites with different Ce weight percentages (2, 4, 6 and 8%) were synthesized by sol-gel method. The influence of cerium inclusion on the structural, morphological, optical properties and elemental composition has been analyzed via XRD, BET surface area analysis, UV-DRS, HR-SEM, EDAX, TEM, Raman and photoluminescence spectra. The structural study showed that all the CeO2–TiO2 nanocomposites crystallized in tetragonal structure with anatase phase. Morphological study revealed that the nanocomposites are in spherical shape with size between 13–15 nm. Raman and PL spectra confirmed the presence and influence of oxygen vacancy defects. The adsorption ability of the CeO2–TiO2 nanocomposites was investigated for congo red dye under dark condition. CeO2–TiO2 nanocomposites have enhanced adsorptive performance in comparison with bare TiO2 nanoparticles. The enhanced adsorptive activity of CeO2–TiO2 nanocomposites is due to the higher surface area of the nanocomposites and oxygen vacancies present in the surface of the nanocomposites. The pseudo second order kinetic equation fits well with higher correlation coefficient compared to the pseudo first order in explaining the reaction kinetics.

BACKGROUND Dye wastewater is causing a serious problem to the environment and to human health. A considerable amount of colored wastewater is generated from many industries. Moreover, many dyes in the wastewater are believed to be toxic and even carcinogenic. Therefore, the removal of dyes from wastewater is necessary and urgent. RESULTS The adsorption kinetics, isotherms and intra‐particle diffusion model were determined from experimental data, and the results indicated that the pseudo‐second‐order kinetic model and the Langmuir adsorption isotherm matched well the adsorption of MB onto GO/MOFs. Thermodynamic parameters revealed that the adsorption of MB by GO/MOFs was spontaneous and exothermic. The adsorption capacity was greatly improved in acidic or alkaline aqueous solution. The maximum adsorption capacity of GO/MOFs reached 274 mg g‐1, higher than most previously reported adsorbents. Also, the adsorbent could be used at least five times after washing with ethanol. CONCLUSION A microwave‐assisted ball milling method was used successfully to synthesize Ni‐MOFs and GO/MOFs. Because of electrostatic interaction and acid–base interaction, both acidic and alkaline aqueous solutions were found to favor the adsorption of MB by GO/MOFs, this being different from previous reports. GO/MOFs also showed acceptable reusability after being regenerated by ethanol. All the results suggest that MOFs prepared by microwave‐assisted ball milling give the prospect of removal of MB from aqueous solution. © 2017 Society of Chemical Industry
