Abstract

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.
