“…Methylene blue (MB) is a cationic dye that is commonly used to color wool and cotton in the textile and paper industries [4]. It is known that MB is very harmful to human health because it can cause vomiting, shock, diarrhea, increased heart rate, tissue damage and carcinogenic causes [5,6].…”

To address environmental pollution, we developed Ni/Al layered double hydroxide-graphene oxide (Ni/Al-GO) adsorbent materials for the purpose of eliminating methylene blue (MB) dye pollutants. The adsorption process was explored by examining many experimental factors, including temperature, regeneration/reuse procedure, pH, and time, and their effects on the material. The appropriate model for the isotherm is the Langmuir isotherm. The Ni/Al-GO material achieved a maximum adsorption capacity of 61.35 mg/g for MB dye at a temperature of 60 °C. The thermodynamic characteristics indicate that the adsorption process is both endothermic and spontaneous as the temperature increases. The regeneration method demonstrated that the Ni/Al-GO material has a highly stable structure, enabling it to be utilized for five cycles with a remarkable regeneration rate of 93.49% in the fifth cycle. The pH that yielded the best results for all materials was pH 10, and the kinetic model demonstrated a pseudo second-order behavior.

“…Methylene blue is a clothing dye that is widely used in the textile industry to dye wool and cotton fabrics. However, dye waste containing methylene blue exhibits toxic properties that can endanger human safety [4]. Methylene blue, a commonly used organic compound and cationic dye, is known to be toxic, carcinogenic, and non-biodegradable, and poses a significant danger to environmental and human safety [5].…”

Degradation of methylene blue has been extensively studied by using TiO2 thin film as photocatalyst deposited onto non-conductive substrates. In this research, we proposed to utilize TiO2 thin film deposited onto conductive substrate, i.e., PCB. We compared concentration degradation between TiO2 thin film deposited onto conductive and non-conductive substrates. In this study, a photocatalysis process was carried out to decompose methylene blue pollutants. This research aims to obtain the performance of TiO2 photocatalyst coated with spray coating method on conductive and non-conductive substrates using UV-C light. This research begins with the manufacture of photocatalysis reactor, manufacture and coating of substrate, manufacture of methylene blue solution, concentration calculation. In this study, two types of thin layer substrates were made using the spray coating method. The first substrate is made using acrylic material as a non-conductive substrate, the second material uses a conductive substrate, PCB. The results shows that concentration of conductive and non-conductive substrates decreases 51% and 33,3 %, respectively. Therefore, conductive substrate may increase photocatalytic process. The use of substrates that are conductors can conduct electrons well, so that when interacting with TiO2, electrons generated by the photocatalysis process can move more easily. Acrylic and PCB materials are distinguished based on the ability to conduct electricity. Acrylic as an insulator and PCB acts as a conductor substrate.

We established three nano-solid adsorbents: nanocellulose based on plant loofah sponge (NC), chitosan (CS), and nanocellulose/chitosan composite (CSC). These substances were employed as solid adsorbents to eliminate methylene blue (MB) dye from wastewater. Various characterization techniques were employed to investigate all the synthesized solid adsorbents, including TGA (thermogravimetric analysis), XRD (X-ray diffraction spectra), (BET) nitrogen gas adsorption-desorption, SEM (scanning electron microscope), TEM (transmission electron microscopy), FTIR (Fourier transform infrared) spectrometer, and zeta potential. According to our results, CSC showed greater thermal stability than LS and NC but lower than CS, mesoporous (2.012 nm), higher total pore volume (0.366 cm3. g− 1), specific surface area (639.3 m2. g− 1), and pHpzc of 7.22. The static adsorption of MB was well described by the Langmuir (R2 > 0.9872), Temkin (R2 > 0.9668), and Dubinin-Radushkevich (R2 > 0.9485) models. The composite of nanocellulose and chitosan exhibited the highest Langmuir adsorption capacity (301.20 mg. g− 1) at 47 °C after a 24 h shaking period at a dosage of 2 g. L− 1 as the adsorbent and pH of 7. The adsorption of MB by the fabricated solid materials fitted well with the linear PSO (R2 > 0.9806) and Elovich (R2 > 0.9574) kinetic model. The enthalpy, entropy, and free energy change for the adsorption of MB onto CSC were determined to be 47.11 kJ. mol− 1, 0.172 kJ. mol− 1. K− 1, and − 3.29 kJ. mol− 1, respectively at 20 °C. Thermodynamic investigation showed that MB adsorption is spontaneous, endothermic, favorable (0 < RL<1, 0.017–0.313), and physisorption (EDR < 8 kJ. mol− 1). Compared to the other eluents, nitric acid produced the highest desorption percentage (98.5%).
