Lead removal from wastewater by Orange peel adsorbent
Keywords:
Lead, Orange peel, Rhodamine B Adsorption, Natural adsorbent, pH, Contact time, Feed concentratioAbstract
In this paper, Lead removal has been studied using Orange peel OP as an adsorbent. In addition, the effect of operating parameters including pH, contact time, and the concentration of lead on adsorption rate have been examined. Orange peel powder OP has demonstrated significant potential as an eco-friendly and efficient material for Lead removal from wastewater. Under the optimum conditions, maintaining a pH of 5, and providing a contact time of 6 hours, Lead removal efficiency exceeding 70% were achieved by using 4 grams of OP. These findings underscore the viability of OP as a sustainable solution for wastewater treatment, particularly for applications involving moderate Lead contamination levels.
