Özet:

 This study demonstrated the efficacy of leftover orange peel in removing Pb2 ions from aqueous solutions. The effects of contact time, starting metal ion concentration, and pH on adsorption effectiveness were investigated. A starting concentration of 800 mgL, a contact time of 90 minutes, and a solution pH of 4.32 were found to be the best working conditions for the removal of the Pb2 ion. In order to examine the surface characteristics of the orange peel, SEM, energy dispersion spectroscopy, and Fourier transform infrared spectroscopy were all used FT-IR. The outcomes showed that the isotherm data was sufficient for the Langmuir isotherm model, which deals with chemical adsorption and the likely irreversibility of the process. The Pb2 ions adsorption capacity was found to be 35.842, 35.714, and 35.087 mgg at 318, 308, and 298 K, respectively. Pseudo-second order, which had the highest coefficient of regression and best described the kinetic data for Pb2 adsorption. Thermodynamic investigations revealed that the removal of the Pb2 ion from orange peel was a natural and exothermic process. Due to its great taking away capability, leftover orange peel has been discovered to be an effective and promising material for the absorption of Pb2 ions from the aqueous environment. It is also simple to get and inexpensive.

 Bu çalışmada, Pb2 iyonlarının sulu çözeltilerden uzaklaştırılmasında atık portakal kabuğunun APK etkin bir şekilde değerlendirilmesi ve geri dönüşüme kazandırılması anlatılmaktadır. Adsorpsiyon verimliliği için; metal iyonu başlangıç derişimi, temas süresi, pH etkisi gibi farklı parametrelerin sonuçları incelendi. Pb2 iyonunun uzaklaştırılmasında en uygun çalışma koşulları; metal iyonu başlangıç derişimi 800 mgL, temas süresi 90 dakika ve çözelti pHı 4,32 olarak belirlendi. APKnın yüzey özellikleri, Fourier dönüşümlü kızılötesi spektroskopisi FTIR, taramalı elektron mikroskobu SEM ve enerji dağılım spektroskopisi ile araştırıldı. Elde edilen veriler izoterm verileri incelendiğinde, işlemin olası tersinmezliğine ve kimyasal adsorpsiyona karşılık gelen Langmuir izoterm modeline uygun olduğunu gösterdi. 298, 308 ve 318 Kde Pb2 iyonu için adsorpsiyon kapasitesi sırasıyla 35,842, 35,714 ve 35,087 mgg olarak hesaplandı. En iyi kinetik veriler, Pb2 adsorpsiyonu için en yüksek regresyon katsayısına sahip yalancı ikinci dereceden denklem ile tanımlandı. Termodinamik çalışmalar, APK kullanılarak Pb2 iyonlarının uzaklaştırılması işleminin doğal ve endotermik bir süreç olduğunu gösterdi. APK nın yüksek uzaklaştırma kapasitesi, kolay bulunması ve ucuz olması nedeniyle sulu ortamdan Pb2 iyonlarının uzaklaştırılmasında etkili ve umut verici bir malzeme olduğu tespit edildi.
