Özet:

 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 800C, 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 m2g and microporous structure 0.738 cm3g, 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 DR 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 kjmol. 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 mgg. This adsorption capacity has a higher adsorption capacity compared to other adsorbents.

 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 800C sıcaklıklarda sabit NaOH oranı ile sıcaklığın etkisi belirlenmiştir. Ardından 600 Cde farklı oranlarda NaOH kimyasalı eklenerek hazırlanan AKın 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 AKların fiziksel ve kimyasal özelliklerinin önemli ölçüde aktivasyon sıcaklığına bağlı olduğu ve NaOH miktarının etkili olduğu belirlenmiştir. En yüksek BET yüzey alanına 1415 m2g, mikro gözenekli yapıya 0,738 cm3g sahip AK elde etmek için optimum koşullar 600 Cde 1:2 oranında başlangıç maddesi: aktivasyon kimyasalı elde edilmiştir. En yüksek yüzey özelliklerine sahip AKın Langmuir, Freundlich ve DR izoterm modellerinin R2 değerleri sırasıyla 0,998, 0,997 ve 0,867dir. Bu ürün için D-R izoterm modelinden hesaplanan adsorpsiyon enerjisi E 6.352 kjmoldür. 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 AKın reaktif turuncu 12 RT 12 için Langmuir adsorpsiyon kapasitesi 256 mggdır. Bu adsorpsiyon kapasitesi diğer adsorbentlerle karşılaştırıldığında daha yüksek adsorpsiyon kapasitesine sahip olduğu belirlenmiştir.
