Summary: In this research, cinnamon nanocellulose was used to remove methyl orange from aqueous solution. The nanocellulose was prepared by hydrolysis and treatment of microcellulose, and characterized by various techniques. The synthesized nanocellulose exhibited high efficiency in decolorizing methyl orange, and the effects of different parameters were investigated. The results showed that nanocellulose could effectively remove methyl orange under optimized conditions, and it also demonstrated structural stability and reusability.

Summary: Hybrid composites of ZnO and PANI were prepared by cost-effective and environmentally-friendly methods, and their structure and morphology were studied. Decreasing particle size and increasing grinding time resulted in reduced photoluminescence intensity and electron-hole recombination. The percentage of PANI also influenced the photocatalytic degradation reaction.

Summary: The degradation performance of Fe-Nb-Cu-Si-B amorphous alloy powders for methyl orange in an ultrasonic Fenton-like process was studied. The effects of pH, H2O2, catalyst dosage, temperature, dye concentration, and ultrasound on the degradation efficiency were investigated. The results show that the amorphous alloy has potential application in the degradation of azo dyes.

Summary: An electroactive dynamic membrane (EADM) was developed using domestic wastewater as inoculum, and it achieved simultaneous solid-liquid separation and contaminants removal through electrostimulation. The EADM system exhibited stability in chemical oxygen demand (COD) removal performance and robustness in response to fluctuating organic load. The introduction of a weak electrical field significantly reduced the transmembrane pressure (TMP) of the EADM compared to the control dynamic membrane (CDM) system.

Summary: The commercial processing of biomaterials produces wastewater containing azo dyes and hydrolyzed by-products. Current treatment methods lack selectivity and efficiency. Microbial-assisted methods, such as the use of Agrobacterium strain JAS1, have been identified as a potential solution for degrading azo dyes and their by-products.

Summary: In this study, corn straw biochar (BC) was prepared by high-temperature pyrolysis and titanium dioxide/biochar composites (TiO2/BC) were prepared by ultrasonic assisted vacuum impregnation. The TiO2/BC(650) composite exhibited good crystal structure and larger specific surface area compared to pure TiO2. It showed improved band edge absorption and excellent light absorption properties. The photocatalytic degradation performance of the TiO2/BC composites, particularly TiO2/BC(650), was evaluated and found to have a high photocatalytic activity in the removal of the simulated organic pollutant.

Summary: This study investigated the decolorization and detoxification effect of Stenotrophomonas acidaminiphila EFS1 strain on methyl orange (MO), and its potential application in the biological treatment of dye wastewater. The results showed that the strain had a high decolorization rate of 80% for MO under constant temperature and oscillation. The decolorization occurred through the breaking of azo bonds and the formation of new colorless compounds. The decolorized metabolites of the strain did not have any obvious toxic effects on test plants.

Summary: This study explored the influence of the composition and structure of natural one-dimensional silicate minerals on the adsorption performance of methyl orange dyes, revealing that the difference in electronegativity between Al3+ and Mg2+ in the crystal structure leads to HNTs and ChNTs having different adsorption capacities.
