In this study, a nanostructure adsorbent was fabricated from mixed nanosized zero‐valent iron (nZVI), chitosan (CS), and copper (Cu) for the simultaneous removal of Reactive Violet 5 and Reactive Blue 171 from the aqueous media. The prepared adsorbent was characterized by scanning electron microscopy, energy‐dispersive X‐ray spectroscopy, Brunauer‐Emmett–Teller, Fourier transform infrared spectroscopy, and X‐ray diffraction. The impact of variables, including pH, adsorbing dosage, contact time, and temperature on the removal percentages of RV5 and RB171 dyes were simultaneously investigated using response surface methodology (RSM) based on a central composite design. The maximum removal efficiency (77.67 %) was obtained at a pH of 3, an adsorbent dosage of 0.3 g, a contact time of 15 min, and a temperature of 10 °C. The adsorption process fitted well with the Langmuir isotherm model with a coefficient of determination (R2) equal to 0.9996 and the pseudo‐second‐order kinetic model (R2=0.9988). Hence, it could be concluded that the process of adsorption mechanism is monolayer and chemical. The maximum adsorption capacity (qmax) was 50.25 mg g−1. In conclusion, nZVI‐CS‐Cu can be considered as an efficient and inexpensive adsorbent for dye removal from aqueous solutions, because its separation is quick and easy, it possesses high efficiency, and there is no secondary pollution.

<p>In this study, the basic fusion dye was adsorbed from wastewater using turmeric leaf waste biochar and the experimental outcomes were fitted with isotherm and kinetics. Further, Response Surface Methodology (RSM) was also performed to analyse the concurrent interactive effects of the process variables. Pyrolysis of turmeric leaf waste biomass resulted in biochar yield of 44.65% at temperature of 300 °C. The biochar had moisture content of 4.21%, volatile matter of 45.38%, ash content of 17.74% and fixed carbon of 32.65% respectively. The batch adsorption studies showed maximum dye removal of 87.44 % and 71% at temperature of 35 °C, dosage of 0.3g, time of 60 min, pH of 7 and dye concentration of 50 ppm respectively for biochar and biomass respectively. The experimental data obtained at equilibrium condition fitted well in pseudo-second order and Langmuir isotherm with R2 value of 0.98 respectively. This study provides base for usage of turmeric leaf-based waste for synthesis of biochar and for effective removal of dye from aqueous environment.</p>

“…This is the most common dye used in the paper and textile industry. It has been concluded that this dye can cause harmful effects on flora and fauna and had a carcinogenic effect on human health [15]. There are a lot of conventional strategies such as membrane-filtration, biological oxidation, coagulation, and adsorption used for dye-industrial effluent treatment [16].…”

Among the biggest issues facing the world now are fuel shortages and water contamination. Therefore, the goal of the current study was directed to produce bioethanol from Jatropha curcas leaves and use the residual wastes in the form of composite sheets for crystal violet (CV) removal. The leaves were collected from Jatropha curcas, irrigated by various irrigation sources; sewage-water (A), sewage-water-sludge (B), and tap water (C). The acid hydrolysis (4% H2SO4) of these leaves demonstrated that the hydrolysis of the Jatropha curcas leaves (A) produced higher values of total reducing sugars (≈ 21 g/l) than other leaves (B &C). Moreover, the bioethanol concentrations obtained from the fermentation of this hydrolysate (A) at the bioreactor scale using Candida tropicalis and Saccharomyces cerevisiae (≈10 and 7 ml/l, respectively) were relatively increased compared to the flask level (≈7 and 5 ml/l, respectively). Afterwards, the unhydrolyzed wastes were dried, grinded, and embedded in polyvinyl chloride (PVC) polymer forming sheets. The sheets were characterized using FT-IR, SEM, swelling, and porosity. The highest CV removal percent of 95.39%, after optimization, was achieved at 100 ppm crystal violet concentration using 2.5 g/l from PVC-A composite sheet after 180-min contact time.
