Summary: In this study, barley seeds and barley biochar were utilized for the removal of textile finishing dyes in aqueous solutions. The adsorption equilibrium data fitted well with Langmuir and Freundlich isotherm models, and the adsorption process followed pseudo-second-order kinetics. Thermodynamic results showed that the removal of dyes on barley was endothermic and spontaneous.

Summary: Textile production is a major industry, but the dyeing process generates a large amount of highly colored wastewater. This study investigated the removal efficiency of five different textile dyes from wastewater using electrocoagulation. The overall removal trend was DO30 > VB1 > AB324 > RB5 > BY28. Encouraging the use of easily removable dyes can preserve water quality and reduce wastewater treatment costs.

Summary: An integrated electrocoagulation-membrane (ECM) system is proposed for treating dye wastewater in the textile industry. The study uses statistical techniques and JMP software to evaluate the feasibility and cost-effectiveness of the system. The results show that the ECM system has lower costs and can effectively remove dyes, but the standalone EC system is more economically feasible.

Summary: Complex dyes have a negative impact on the environment and are difficult to remove using traditional methods. A series of experiments was conducted to determine the optimal parameters for the removal of direct blue 78 dye using chemically treated coal fly ash (TCFA). A pilot plant was designed and implemented to investigate the ability of TCFA to remove pollutants from textile wastewater. Various physical and chemical analyses were conducted on the fly ash. The results showed that chemical treatment significantly improved the properties of the fly ash. Batch adsorption experiments demonstrated that TCFA was effective in removing dyes under optimal conditions.

Summary: Dye wastewater is a challenging pollutant, and the development of efficient and low-cost adsorbents is crucial. A novel electrocoagulation method was introduced for fabricating Ni-Fe LDH from nickel plating wastewater, which exhibited remarkable removal efficiency for Congo red wastewater. The adsorption mechanism of Ni-Fe-10 mainly depended on electrostatic attraction, ion exchange, and H-bonding.

Summary: Direct current (DC) electrocoagulation is effective in decolorizing indigo dyeing wastewater but has low chemical oxygen demand (COD) removal rate and high energy consumption due to electrode corrosion. To improve COD removal rate and reduce energy consumption, a peroxi-alternating current (AC) electrocoagulation (EC) system was developed. The study focused on the effects of power type, electrode combination, and process parameters on COD removal rate and decolorization rate, and investigated the COD degradation mechanism. Results showed that AC electrocoagulation enhanced floc adsorption capacity and achieved a COD removal rate of 51.19%. The coupled peroxi-AC electrocoagulation system further removed sulfite and residual dyes, reaching COD removal and decolorization rates of 78.09% and 98.47%, respectively. The system also had significantly lower energy consumption compared to DC electrocoagulation, with a reduction of 70%. Overall, the peroxi-AC EC system is an effective method for reducing COD concentration in indigo dyeing wastewater.

Summary: This study investigated the removal of polyamide microplastics from wastewater using electrocoagulation. The combination of iron anode and aluminum cathode (Fe-Al) exhibited the highest removal efficiency. The removal efficiency of microplastics increased with higher applied voltage and electrolyte concentration. The optimized conditions for polyamide removal were using Fe-Al electrodes, with a plate spacing of 2.5 cm, an applied voltage of 10 V, an initial pH of 7, and an electrolyte concentration of 0.02 mol/L. This study highlights the potential of electrocoagulation for microplastics removal and provides insights for operational parameter optimization.

Summary: In this study, the influence of oxygen and ozone as oxidizing agents in combination with electrocoagulation for the treatment of textile wastewater was compared. The results showed that there was no significant difference in the removal efficiency of color, dissolved organic carbon, and UV when both oxidants were used. The amount of iron generated by electrocoagulation and its oxidation in the presence of air or ozone were found to be key factors for contaminant removal.

Summary: Oxidative stress caused by reactive oxygen species (ROS) can lead to cell death, lipid peroxidation, and damage to physiological mechanisms in the human body. Malondialdehyde (MDA) is widely used as a biomarker for measuring oxidative stress. This study proposes a new method using para methoxy aniline (PMA) to convert MDA to a detectable adduct and applies response surface methodology (RSM) and artificial neural network (ANN) to model and predict MDA detection.

Summary: MIL-53(Fe) was synthesized as a three-dimensional metal-organic framework with different precursors-to-solvent ratios, denoted as MIL53B and MIL53C. Modified versions, MIL53B/NH2 and MIL53C/NH2, with varying NH2 ratios (0.10, 0.20, and 0.30), were also prepared using organosilane. The materials were characterized using XRD, SEM, EDS, and FTIR techniques, and their adsorption capacity for dye (Direct Red 23) was studied. The modified MIL53 showed higher adsorption capacity (4,989 mg/g) compared to the unmodified version (1,375 mg/g), indicating its potential as a dye adsorbent and for removing similar organic molecules from contaminated water.
