Aktif Karbon;
yapısında karbon içeren her türlü doğal ya da sentetik başlangıç maddesinden
üretilebilen, sahip olduğu geniş iç yüzey alanı ve farklı çaplardaki gözenek
sayısı sayesinde sıvı ve gaz uygulamalarında sıklıkla kullanılan bir
adsorbandır. Bu çalışmada ülkemizde bolca üretilen şeftali meyvesinin
çekirdeğinden çinko klorür ile kimyasal aktivasyon sonucu aktif karbon
üretilmiştir. 3/1 emdirme oranı ve farklı karbonizasyon sıcaklıklarında
(400°C, 500°C, 600°C) üretilen aktif karbonların gözenek hacmi, BET yüzey
alanı, ortalama gözenek çapı ve gözenek boyut dağılımı gibi yapısal
özellikleri araştırılmıştır. Şeftali çekirdeği ve aktif karbon azot gazı
adsorpsiyonu, SEM görüntüleri, FTIR analizleri ve elementel analiz sonuçları ile
karakterize edilmiştir. En yüksek yüzey alanına sahip (946 m2/g)
aktif karbon, 500 °C ve 3/1 emdirme oranında elde edilmiştir. Sonuç olarak şeftali çekirdeğinden kimyasal aktivasyon
yöntemiyle yüksek yüzey alanı ve gözenek hacmine sahip aktif karbonlar
üretilir, böylece bitkisel artıkların değerlendirilmesi sağlanmış olur.
