“…This can be attributed to the saturation of the active sites on the surface of the silicon dioxide nanoparticles, limiting further adsorption of dye molecules from the contaminated solution. On the basis of these findings, it can be concluded that an optimum dosage of 0.1 g of prepared silicon dioxide nanoparticles ensures the highest treatment efficiency for aqueous solutions contaminated with bromophenol blue dye (Ibrahim et al, 2021).…”

“…These materials include banana peels (Abdullah et al, 2023) (Abdulkareem et al, 2023). A wide range of contaminants can be remediated by agricultural and industrials wastes, such as phenols (Ho, 2022), inorganic toxic (Alalwan et al, 2020), heavy metals (Hashem et al, 2021), hardness (Ibrahim et al, 2021), etc. Although the accumulation of these residues laden with toxic pollutants after the end of the adsorption process generated an additional problem that required disposal, the concept of the zero-residue level opened new horizons for benefiting from these residues (Hamdi et al, 2024).…”

The present study focused on the synthesis of silicon dioxide nanoparticles (SiO 2 ) using a green method, incorporating buckthorn leaves extract and potassium metasilicate (K 2 SiO 3 ) as the precursor. A comprehensive characterization of the prepared nanoparticles was performed using X-ray diffraction (XRD), fourier-transform infrared spectroscopy (FTIR), field emission scanning electron microscopy (FESEM), Brunauer-Emmett-Teller (BET) analysis, and dynamic light scattering (DLS). The results confirmed the purity of the SiO 2 nanoparticles and exhibited a range of diverse functional groups on their surface. Furthermore, the average size and surface area of the nanoparticles were determined to be 35.8 nm and 246 m 2 •g -1 , respectively. These well-characterized SiO 2 nanoparticles were employed as an effective adsorbent for the removal of bromophenol blue dye from aqueous solutions in a batch mode adsorption unit, under varying operating conditions. The factors considered for evaluating the efficiency of SiO 2 nanoparticles as an adsorption media included pH, contact time, agitation speed, dye concentration, temperature, and the quantity of nanomaterial utilized. Experimental findings demonstrated a remarkable removal efficiency of 96% for bromophenol blue dye at an initial concentration of 100 ppm in the contaminated solution. Interestingly, the percentage removal exhibited an inverse relationship with dye concentration and temperature, while being directly proportional to other factors. Overall, the green-synthesized silicon dioxide nanoparticles proved to be a promising adsorbent for the effective removal of bromophenol blue dye from aqueous environments. The findings highlight the potential application of these nanoparticles in wastewater treatment and pollution mitigation, offering a sustainable and eco-friendly solution for environmental challenges.

“…By plotting the relationship between concentration and absorbance, getting a straight line representing the calibration curve. The method described by [39] [40] was adopted, where a spectrophotometer (NU-T3A, NANBEI, China) of ±1nm wavelength accuracy was used to determine the concentrations of perchlorate at 292 nm wavelength. All samples were tested triplicate and the arithmetic mean was taken to reduce the error rate.…”

The ability to remove perchlorate anions was investigated by the adsorption technique in a laboratory scale and by a batch type unit from contaminated aqueous solutions prepared at specific concentrations. The adsorption process was carried out using banana peels, which were chosen as an available, cheap, and lowcost adsorption media. The studied operating conditions in the treatment process were the acidic function, shaking speed, contact time, temperature, in addition to the initial concentration of perchlorate, which ranging from 1-10, 100-400 rpm, 10-180 min, 20-50 ºC, 50-1000 ppb respectively, while the dose of adsorbent media ranged between 0.5-6 g and the particle size ranged from 0-Pan. The experimental results showed that the removal efficiency of perchlorate changes directly with the shaking speed, contact time, particle size and the dose of adsorbent, while it was inversely with the remaining variables for certain levels. Thus, two types of contaminants were disposed of simultaneously in a beneficial, and eco-friendly manner, reaching to Zero Residue Level (ZRL).

“…Among the fruit residues used to produce bioethanol are grapes, so there are many research studies on the production of ethanol from it, including Korkie et al [55] identified and analyzed yeast strains from grape pomace on their capacity to hydrolyze the complex polysaccharides in grape pomace and use the fermentable sugars to form ethanol. Two isolates of Pichia rhodanese could partly hydrolyze the pomace polysaccharides, although fermentation of the pomace resulted in only a modest increase in ethanol production.…”

The importance of this research lies in keeping pace with the global trend to diversify energy sources and reduce climate change and air pollution by shedding light on how to benefit from agricultural waste by using it as a raw material for the production of bioethanol, which is one of the most important types of renewable fuels. This review highlighted the; ways of converting agricultural and fruit waste into bioethanol and its environmental and economic benefits-including adding it to gasoline used as car fuel in different proportions, as it works to raise the octane number of gasoline and improve its quality, thus reducing its production costs and reducing gas emissions from vehicle exhaust. In addition, the global production of bio-ethanol was reviewed and is expected to reach it by the end of 2023. It also highlighted the results of several studies that dealt with the properties and uses of ethanol and the best agricultural wastes used for this purpose. It is suggested to focus on the agricultural waste in Iraq, such as rice husks, in terms of cost and conditions for improvement to increase bio-ethanol production using fermentation processes.
