Bu çalışmada, bitkisel bir atık olan doğu mazısı aktif karbon (AK) ürününe dönüştürülmeden önce kurutma ve öğütme işlemleri ile kimyasal aktivasyon işlemi için hazır hale getirilmiştir. 600 ve 800°C sıcaklıklarda sabit NaOH oranı ile sıcaklığın etkisi belirlenmiştir. Ardından 600 °C'de farklı oranlarda NaOH kimyasalı eklenerek hazırlanan AK’ın ürünlerinin yapısal ve morfolojik özellikleri termal gravimetrik analiz (TGA), fourier transform infrared spektroskopisi (FT-IR), alan emisyonlu yüzey elektron mikroskobu (FE-SEM) teknikleri ile Brunauer - Emmett - Teller (BET) spesifik yüzey alanı, gözenek boyut dağılımı yöntemleri ile araştırılmıştır. Piroliz sıcaklığı ve NaOH kütle oranının AK üzerindeki etkisi araştırılmıştır. Karakterizasyon sonuçlarına göre hazırlanan AK’ların fiziksel ve kimyasal özelliklerinin önemli ölçüde aktivasyon sıcaklığına bağlı olduğu ve NaOH miktarının etkili olduğu belirlenmiştir. En yüksek BET yüzey alanına (1415 m2/g), mikro gözenekli yapıya (0,738 cm3/g) sahip AK elde etmek için optimum koşullar 600 °C'de 1:2 oranında (başlangıç maddesi: aktivasyon kimyasalı) elde edilmiştir. En yüksek yüzey özelliklerine sahip AK’ın Langmuir, Freundlich ve D–R izoterm modellerinin R2 değerleri sırasıyla 0,998, 0,997 ve 0,867’dir. Bu ürün için D-R izoterm modelinden hesaplanan adsorpsiyon enerjisi (E) 6.352 kj/mol’dür. RT 12 'nin AK tarafından adsorpsiyonunun Langmuir izoterm modeliyle daha iyi modellendiğini, adsorbent yüzeyinde tek tabaka halinde absorplandığı ve D-R izoterm modelinden elde edilen sonuçlara göre fiziksel adsorpsiyonun rol aldığını tespit edilmiştir. En yüksek yüzey özelliklerine sahip AK’ın reaktif turuncu 12 (RT 12) için Langmuir adsorpsiyon kapasitesi 256 mg/g'dır. Bu adsorpsiyon kapasitesi diğer adsorbentlerle karşılaştırıldığında daha yüksek adsorpsiyon kapasitesine sahip olduğu belirlenmiştir.

Öz

In this study, Thuja orientalis cone, an agricultural waste, was prepared for chemical activation process by drying and grinding processes before being converted into activated carbon (AC) product. At 600 and 800°C, the effect of temperature was determined with constant NaOH ratio. Then, the structural and morphological properties of AC products prepared by adding NaOH chemical at different ratios at 600 °C were investigated by thermal gravimetric analysis (TGA), fourier transform infrared spectroscopy (FT-IR), field emission surface electron microscopy (FE-SEM) techniques and specific surface area and pore size distribution techniques. According to the characterization results, it was determined that the physical and chemical properties of the prepared ACs significantly depend on the activation temperature and the amount of NaOH is effective To obtain AC with the highest specific surface area (1415 m2/g) and microporous structure (0.738 cm3/g), optimum conditions were obtained at 600 °C in a ratio of 1:2 (starting material: activation chemical). The R2 values of the Langmuir, Freundlich and D–R isotherm models of AK, which have the highest surface properties, are 0.998, 0.997 and 0.867, respectively. The adsorption energy (E) calculated from the D-R isotherm model for this product is 6.352 kj/mol. It was determined that the adsorption of reactive orange 12 (RO 12) by AK was better modeled with the Langmuir isotherm model, that it was absorbed as a monolayer on the adsorbent surface, and that physical adsorption played a role according to the results obtained from the D-R isotherm model The Langmuir adsorption capacity for RO 12 of AK, which has the highest surface properties, is 256 mg/g. This adsorption capacity has a higher adsorption capacity compared to other adsorbents
