Abstract

Bu çalışmada, Thuja Orientalis kozalağı aktif karbon hazırlamada başlangıç maddesi olarak değerlendirilmiştir. Thuja Orientalis kozalakları kurutma ve öğütme işlemlerinden sonra 500 °C’de ZnCI2 ile farklı oranlarda emdirilerek aktive edilmiştir. ZnCI2 miktarının elde edilen ürünlerin yapısı ve morfolojisi üzerine etkileri FT-IR, SEM ve BET ve zeta potansiyeli teknikleri kullanılarak incelenmiştir. Aktivasyon işlemleri sonucunda, Thuja Orientalis kozalaklarının ZnCI2 ile kütlece 1:2 oranında emdirilmesi sonucu elde edilen ürünün en yüksek yüzey alanına (1195 m2/g) ve mikro gözenek hacmine (0.599 cm3/g) sahip aktif karbon olduğu tespit edilmiştir. Bu aktif karbonun farklı deneysel şartlar altında sudaki reaktif mavisi 49 giderim verimi araştırılmıştır. Reaktif mavisi 49’un giderimin de aktif karbonun giderim kapasitesi Langmuir izoterm modeline göre 95.239 mg/g’dır. Elde edilen aktif karbonun giderim kapasitesinde bir değişiklik olmadan en az on kez adsorpsiyon-desorpsiyon döngüsünde kullanılabilir olduğu belirlenmiştir.

PREPARATION OF ACTIVETED CARBON FROM THUJA ORIENTALIS CONE AND USING FOR REMOVAL REACTIVE BLUE 49 FROM WATER

Abstract

In this study, Thuja Orientalis cone was evaluated as the starting material in the preparation of activated carbon. Thuja Orientalis cones were activated by impregnation with ZnCl2 in different rations at 500 °C after drying and grinding processes. The effects of the amount of ZnCl2 on the structure and morphology of the products obtained were investigated using FT-IR, SEM and BET and zeta potential techniques. As a result of the activation process, the product obtained by impregnating Thuja Orientalis cone with ZnCl2 in a ratio of 1:2 was found to have the highest surface area (1195 m2/g) and micropore volume (0.599 cm3/g) of activated carbon. The removal efficiency of reactive blue 49 in water under different experimental conditions was investigated. The removal capacity of the adsorbent in the removal of reactive blue 49 is 95.239 mg/g according to the Langmuir isotherm model. The resulting activated carbon was found to be usable at least ten times in the adsorption-desorption cycle without a change in removal capacity.
