In order to extract a highly concentrated dye from textile industry wastewater, an electrocatalytic oxidation method based on Ru/Ir/Ti, RuO2/IrO2/TiO2 electrodes and high‐density graphite was used. Optimization of the oxidation process was controlled by varying such parameters as current density, pH, concentration of supporting electrolyte (NaCl), wastewater treatment time. The maximum dye removal from wastewater is achieved at pH 7.1, current density 70 mA cm−2, NaCl concentration 3 g/L, and treatment time 15 minutes. Among the investigated electrodes, the Ru/Ir/Ti anode and titanium‐based oxides of these metals proved to be the most effective. The percentage of color removal for all anodes increases with increasing current density and duration of solution treatment. For a graphite electrode, at a current density of 70 mA cm−2 and a treatment time of 10 minutes, a maximum dye removal of 90 % is achieved. The percentage of color removal for Ru/Ir/Ti and RuO2/IrO2/TiO2 electrodes is higher than for graphite and amounted to 98 % and 92 %, respectively. The results of the electronic structure of the dye made it possible to shed light on the nature of the electronic spectra and the possible mechanism of the electrocatalytic act. Consideration of the dependence of color removal, COD and TOC on such parameters as current density, water treatment time in the reactor showed that the efficiency of the wastewater treatment process increases in the series: graphite<RuO2/IrO2/TiO2<Ru/Ir/Ti. The role of various factors of RedOx processes that affect the degree of dye degradation, as well as chloride ions on the formation of active particles with high chemical energy at the moment of their formation, is discussed.

“…The composition of palm wood consists mainly of total cellulose or holocellulose, making up more than 80% of the fiber, which can be used to produce adsorbent materials. These materials, derived from agricultural waste, have recently garnered attention as beneficial choices for adsorption technology, with various substances being utilized (Amalina et al., 2022). The advantages of using palm powder for adsorption of essential oil are numerous.…”

Palm wood powder derived from palm wood waste was utilized as a novel absorbent material. The investigation involved exploring its pore structure and size to achieve the controlled release of bioactive compounds from plai oil, providing protection against pathogenic bacteria and thereby extending the shelf life of broccoli. The palm wood sachet was prepared before being placed into the broccoli bag. The process to create the sachet involved freezing the palm wood at −10°C and then drying it at a temperature of 200°C. After drying, the material was ground to achieve a particle size of 20 mesh and then packaged into sachets made from wood pulp. The optimized palm wood plai oil sachet (PWPS), measuring 5 × 7 cm, with a thickness of 0.58 µm, was produced by soaking 2 g of palm powder in plai oil at a concentration of 30 µL/mL before drying and packing it inside a 5‐L polyethylene plastic bag (24 × 34 cm) along with broccoli (150 g). The packages were kept at 4°C for 20 days to determine the antimicrobial activity of the PWPS and broccoli quality. PWPS significantly inhibited the growth of Escherichia coli, Salmonella Typhimurium, Staphylococcus aureus, and Listeria monocytogenes in broccoli for at least 20 days. The sachet demonstrated complete inhibition of all bacteria when reused at least two times and an 80% reduction in efficacy after three uses. Moreover, the PWPS controlled the growth of total aerobic bacteria and yeast and mold in broccoli, meeting microbiological criteria for up to 14 days. Broccoli stored with PWPS showed good quality results and contained high antioxidant value. These results demonstrate the potential application of PWPS in controlling food pathogens and spoilage microbes during storage.Practical ApplicationThis study introduces a novel absorbent material made from palm wood powder, addressing the need for utilizing abundant waste palm wood in the food industry. The material benefits the safe transportation of vegetables from farms to markets. Its porous structure allows efficient absorption of plai oil emulsion, ensuring pathogen‐free and high‐quality treated broccoli. The reusable sachets benefit farmers seeking to extend the shelf life of fresh produce. This cost‐effective method utilizes plai oil vapor, making it suitable for large‐scale production.

“…Recently, Tran et al (2017) prepared the AC from pods of GS through two-stage chemical activation with K 2 CO 3 and applied it to remove methylene green 5. To optimally treat, water polluted with sulfamethoxazole, golden shower is better produced with hydrothermal pre-carbonation (Amalina et al, 2022;Du et al, 2023). Compared with other ACs, spherical ACs exhibit several enhanced characteristics such as high mechanical strength, high wear resistance, superior adsorption, low ash content, high purity, smooth surface, high bulk density, low-pressure drop, controllable pore size distribution, and high micropore volume (Chai et al, 2021;Yan et al, 2022).…”

This research aimed to modify activated carbon into oxidated activated carbon because it can effectively remove diclofenac sodium (DCF) and increase the adsorption capability. In this study of the several variations of initial concentration and contact time, those variations affected the optimal result. To determine, the removal efficiency of diclofenac sodium used Golden Shower Activated Carbon based on the contact time variation and the optimum contact time compared to Golden Shower Oxidated Activated Carbon as adsorbent on the batch method and to know the isotherm model and the kinetic model of the adsorbent on the adsorption in diclofenac sodium solution. The pHPZC for GSHAC and GSHOAC were 2.4 and 9.3. The optimum contact time for GSHAC was 225 min with the capacity (qt = 184.71 mg/g). The optimum contact time for GSHOAC was 169 min with the capacity (qt = 188.34 mg/g). The Isotherm model, kinetics model, and the physical characterization of the biosorbent were thoroughly investigated. The isotherm model chosen in the adsorption process for GSHAC and GSHOAC was the Langmuir model (R2 = 0.985 and R2 = 0.973). The pseudo‐second‐order for GSHAC and GSHOAC was confirmed to be a kinetic pseudo‐second‐order model of the adsorption with R2 values of 0.9566 and 0.9986. The model represents that the reaction from the adsorbent to the solution was double the initial concentration. Based on SEM analysis after the adsorption process, it was found that flakes of adsorbent before adsorption had many layers of pores, causing an irregular texture after adsorption showed that GSHAC and GSHOAC were fragmented and had many layers of pores that were closed and tight because it adsorbed DCF.
