Özet:

 The aim of this study was to develop a highly porous activated carbon MPK-AC from corn tassel and cob residues using a two-stage pyrolysis process with CaOH2 as the activating agent and to investigate its application for the adsorption of tetracycline TSL and paracetamol PST from water. The optimal conditions for chemical activation were determined to be a temperature of 700 C and a CaOH₂-to-corn waste ratio of 3:1 ww. The MPK-AC adsorbent, both before and after adsorption, was characterized by Fourier Transform Infrared Spectroscopy FTIR and BrunauerEmmettTeller BET surface area analysis. Reusability of the MPK-AC was evaluated through three consecutive adsorptiondesorption cycles. BET analysis revealed that the synthesized MPK-AC exhibited a mesoporous structure with a total pore volume of 2.013 cm³g, an average pore diameter of 2.963 nm, and a specific surface area of 2358 m²g. Adsorption isotherms and kinetic behaviors were investigated through batch adsorption experiments. The maximum adsorption capacities of MPK-AC were calculated as 1250 mgg for TSL and 588 mgg for PST, indicating a physical adsorption mechanism. Thermodynamic results indicated that the adsorption of TSL was an endothermic process, whereas the adsorption of PST was exothermic.

 Bu çalışmada, mısır püskülü ve koçanı kalıntılarından iki aşamalı piroliz ve CaOH2 aktive edici proses ile elde edilen son derece gözenekli aktif karbon MPK-AK geliştirilmesi ve daha sonra sudan tetrasiklin TSL ve parasetamolü PST uzaklaştırmak için uygulanması amaçlanmıştır. Kimyasal aktivasyon için optimum koşullar 700 C ve CaOH2  mısır atıkları ağırlıkça 31; ww olmuştur. MPK-AK adsorbanı adsorpsiyondan önce ve sonra Fourier dönüşümlü kızılötesi spektroskopisi FTIR ve Brunauer-Emmet-Teller BET analizi ile karakterize edilmiştir. MPK-AK adsorbanının tekrar kullanılabilirlik çalışmaları adsorpsiyon-desorpsiyon döngüleri 3 kez tekrar edilerek değerlendirilmiştir. BET analiz sonuçlarından sentezlenen MPK-AK adsorbanının toplam gözenek hacmi 2.013 cm3g, ortalama gözenek çapı 2.963 nm, özgül yüzey alanı 2358 m2g ile mezogözenekli yapıya sahip olduğu görülmüştür. Adsorpsiyon izoterm ve kinetik çalışmaları kesikli adsorpsiyon toplu deneyleri yapılarak belirlenmiştir. MPK-AKın maksimum adsorpsiyon kapasitesi TSL ve PST için sırasıyla 1250 mgg ve 588 mgg olarak hesaplanmış ve fiziksel adsorpsiyon olduğu sonucuna varılmıştır. Termodinamik sonuçlar TSL adsorpsiyonunun endotermik PST adsorpsiyonunun ise ekzotermik bir işlem olduğunu göstermiştir.
