Industries are among the largest global consumers of water, with a significant portion being converted into industrial wastewater. Paint factories, in particular, major contributors to environmental lead pollution, releasing (II) through untreated effluents. Exposure poses serious health risks, including carcinogenic effects, neurological disorders, blood-related complications, and damage vital organs such as liver, kidneys, lungs. While extensive research has focused on removal from synthetic wastewater, limited studies have addressed application these methods real This study aimed evaluate efficiency Noug stalk activated carbon removing paint factory effluent under optimized conditions. Laboratory experiments were conducted assess performance treating wastewater factory. Statistical analysis using Package for Social Sciences version 20 was employed, paired sample t-test determining significance differences concentrations before after treatment, considering p-value <0.05 statistically significant. The exhibited pH 6.62, temperature 20.40 °C, chemical oxygen demand 1717 mg/L, total suspended solids 710 dissolved 1231 concentration 23.54 mg/L. Results demonstrated 94.84 %, reduction post-treatment (t = 157.62, p < 0.001). These findings highlight potential an effective adsorbent treatment.

Carbon Dioxide Adsorption over Activated Biocarbons Derived from Lemon Peel

Molecules, Год журнала: 2024, Номер 29(17), С. 4183 - 4183

Опубликована: Сен. 4, 2024

The rising concentration of CO2 in the atmosphere is approaching critical levels, posing a significant threat to life on Earth. Porous carbons derived from biobased materials, particularly waste byproducts, offer viable solution for selective adsorption large-scale industrial sources, potentially mitigating atmospheric emissions. In this study, we developed highly porous lemon peel through two-step process, consisting temperature pretreatment (500 °C) followed by chemical activation KOH at 850 °C. largest specific surface area (2821 m2/g), total pore volume (1.39 cm3/g), and micropore (0.70 cm3/g) were obtained highest KOH-to-carbon ratio 4. contrast, sample activated with 2 demonstrated greatest distribution. This biocarbon exhibited superior capacity, reaching 5.69 mmol/g 0 °C 100 kPa. remarkable performance can be attributed micropores diameters smaller than 0.859 nm. Radke–Prausnitz equation, traditionally employed model equilibrium organic compounds liquid solutions, has been shown equally applicable describing gas–solid equilibrium. Furthermore, equations dependence equation’s parameters have developed.

ABSTRACT With a wide range of development opportunities, photocatalytic technology provides potent solution to today's energy and environmental issues. In this study, tin‐doped copper oxide nanoparticle loaded on almond shell activated carbon (Sn: CuO/ASAC) were prepared thoroughly examined described using UV‐DRS, XRD, BET, FT‐IR, SEM with EDS, XPS. Band gap was decreased visible absorbance increased as result Sn‐doping ASAC loading. Therefore, by altering batch experimental conditions such starting pH the quantity Sn‐doped CuO composite, all product samples employed for MB dye degradation from aqueous under sunlight. The obtained results revealed that >99.37% removal over composite sample achieved within 90 min 1.2 g L −1 adsorbent dosage, 40‐mg/L at weakly alkaline values. kinetics study accurately describes rates, revealing high rate constant 0.052 compared other samples. mechanism studied radical scavenging tests Sn: CuO/ASAC. These findings suggested could be considered wastewater treatment technique.
