Vanadium, one of the heavy metals present in crude oil, harmfully affects equipment oil refineries and quality petroleum products. As a result, it is important to innovate effective methods for reducing or removing its concentration. This paper aims study vanadium metal from Iraqi using activated carbon as an adsorbent material. Different experimental factors, i.e., dose, contact time, agitation speed, were regulatory varied evaluate their impact on adsorption efficiency. The outcomes revealed exceptionally good efficacy eliminate vanadium. results exhibited that maximum remediation was 86.33%, recorded at optimum 0.5 g carbon, 400 rpm 75 °C temperature, time minutes. According these findings, has great ability adsorb oil. Thus, can be considered sustainable material treating petroleum. Furthermore, this approach will help by costs eliminating lead corrosion poisoning catalysts.

Petroleum extraction generates substantial quantities of produced water, a challenge compounded by water scarcity in oil-producing regions, notably the Middle East. Leveraging effectively, adhering to environmental standards, can offer viable solution issue scarcity. This study explores potential mandarin peels as an available, cost-effective adsorbent for treating synthetic aqueous simulated oil-field specifically targeting phenol, dangerous pollutant. Employing batch-mode adsorption unit, six operational factors—phenol concentration, acidity, agitation speed, contact time, dose, and temperature—were investigated. Results revealed inverse relationship between phenol removal pH, temperature, while direct correlations were observed with other variables. Mandarin exhibited notable recovery, reaching maximum efficiency 74.43% at pH 1, 450 rpm 38 ppm initial 5 g time 180 minutes, 20°C temperature. Isothermal kinetic analyses favored Langmuir intra-particle diffusion models. Thermodynamically, process proved exothermic, marked low entropy, spontaneous within tested temperature range. Adhering zero residues level concept, exploring beneficial safe disposal methods contaminated led investigating toxic peel residue rodenticide, displaying promising efficacy on laboratory albino rats. Consequently, this proposes sustainable approach, laden pollutants using readily available agricultural waste concurrently repurposing into environmentally friendly material, aligning concept.
