Abstract

The effective removal of heavy metals from water sources is of paramount importance due to their detrimental effects on the environment and human health. In this study, we present a sustainable approach to address this issue by valorizing agricultural waste in the form of pomegranate peel for the synthesis of an activated carbon-based hybrid composite. The pomegranate peel-derived activated carbon exhibited high removal capacities for Pb2+ and Ca2+ ions, with maximum elimination achieved at pH 7 within a pH range of 3 to 11. The adsorption process reached equilibrium in 30 minutes, resulting in remarkable removal efficiencies of 80.3% for Pb2+ and 74.3% for Cd2+. These findings highlight the successful synthesis and characterization of pomegranate peel-derived activated carbon as a promising and environmentally friendly solution for the sustainable removal of heavy metals, emphasizing the significance of agricultural waste valorization in mitigating water contamination.

Valorizing Agricultural Waste: Synthesis of Pomegranate Peel-Derived Activated Carbon-Based Hybrid Composite for Sustainable Heavy Metal Removal

Abstract

Ağır metallerin su kaynaklarından etkili bir şekilde uzaklaştırılması, çevre ve insan sağlığı üzerindeki zararlı etkileri nedeniyle büyük önem taşımaktadır. Bu çalışmada, aktif karbon bazlı hibrit kompozit sentezi için nar kabuğu şeklindeki tarımsal atıkları değerlendirerek bu sorunu ele almak için sürdürülebilir bir yaklaşım sunuyoruz. Nar kabuğundan türetilen aktif karbon, Pb2+ ve Ca2+ iyonları için yüksek giderim kapasiteleri sergilemiş ve 3 ila 11 pH aralığında pH 7'de maksimum giderim elde edilmiştir. Adsorpsiyon süreci 30 dakika içinde dengeye ulaşmış ve Pb2+ için %80,3 ve Cd2+ için %74,3'lük kayda değer giderim verimlilikleri elde edilmiştir. Bu bulgular, nar kabuğundan türetilen aktif karbonun ağır metallerin sürdürülebilir bir şekilde uzaklaştırılması için umut verici ve çevre dostu bir çözüm olarak başarılı bir şekilde sentezlendiğini ve karakterize edildiğini vurgulayarak, su kirliliğinin azaltılmasında tarımsal atıkların değerlendirilmesinin önemini vurgulamaktadır.
