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. Further is necessary explore how presence other heavy metals may affect its investigate column adsorption techniques regeneration processes depletion.

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.

Untreated industrial effluents, particularly from tanneries and heavy industries, are the main source of metal pollution, which poses serious environmental risks. Lead is one most toxic metals, adversely affects human functioning accumulates in environment. This study presents ACUTLaqE (Activated Carbon-Used Tea Leaves Aqueous Extract) as an effective adsorbent for Pb2+ ion removal their aqueous solution. The composite was synthesized by blending activated carbon rice husks with a tea extract solution characterized using SEM, XRD, FTIR spectroscopy. Batch tests demonstrated that highly efficient, removing about 99% ions at dose 2 g/L within 30 minutes. adsorption data conformed well to Langmuir isotherm model, suggesting homogeneous monolayer formation on surface. qm 38.61 mg/g, RL value close 0, indicating favourable adsorption. Thermodynamic parameters showed negative Gibbs free energy (ΔG⁰) values, reflecting spontaneous process. enthalpy (ΔH⁰) entropy (ΔS⁰) changes were 66.86 KJmol-1 257.12 JK-1mol-1, respectively. mechanism involved electrostatic interactions surface complexation composite's hydroxyl carboxyl groups. These findings suggest promising material potentially other metals effluents.
