Özet:

 In this study, it was aimed to obtain Al2O3 from waste Tetra Pak packages by using the hydrometallurgical method. Tetra Pak recycling has become an increasingly researched topic around the world. Cellulose, polyethylene and aluminum, which form the structure of Tetra Pak packages, are raw materials that can be reused after recycling. Cellulose was separated from Tetra Paks structure by hydropulping process and polyethylene was separated from Tetra Paks structure by leaching with HCl, and optimum parameters of these processes were investigated in experimental studies. Aluminum in the structure was dissolved in acid solution with 100 efficiency in the experiments carried out with 0.1750 M and 0.1312 M acid concentration. Aluminum, which was dissolved in acid solution, was obtained as the AlCl3 phase and precipitated as AlOH3 with the addition of 100 stoichiometric NaOH, and the precipitates were calcined at 950 C for 1 hour to obtain the Al2O3 structure. The materials used in the experimental studies and the products obtained as a result of these experiments were analyzed by Atomic Absorption Spectrometry AAS, Fourier Transform Infrared FTIR Spectroscopy, Scanning Electron Microscopy SEM  Energy-Dispersive X-ray Spectroscopy EDS, and optical microscopy techniques.

 Bu çalışmada atık Tetra Pak ambalajlarından hidrometalurjik yöntem kullanılarak Al2O3 elde edilmesi amaçlanmıştır. Tetra Pak geri dönüşümü, dünya çapında giderek daha fazla araştırılan bir konu haline gelmiştir. Tetra Pak ambalajlarının yapısını oluşturan selüloz, polietilen ve alüminyum, geri dönüştürülerek yeniden kullanılabilen hammaddelerdir. Tetra Pakın yapısından selüloz hidropulping prosesi ile, polietilen ise HCl ile liç prosesiyle ayrıştırılmış ve deneysel çalışmalarda bu prosesler için optimum parametreler araştırılmıştır. Yapıdaki alüminyum, 0,1750 M ve 0,1312 M asit konsantrasyonuyla yapılan deneylerde 100 verimle çözünmüştür. Asit çözeltisinde çözünen alüminyum, AlCl3 fazı olarak elde edilmiş ve 100 stokiyometrik NaOH ilavesiyle AlOH3 olarak çöktürülmüştür. Bu çökeltiler Al2O3 yapısı elde etmek için 950 Cde 1 saat kalsine edilmiştir. Deneysel çalışmalarda kullanılan malzemelerin ve bu deneyler sonucunda elde edilen ürünlerin analizleri Atomik Absorbsiyon Spektroskopisi AAS, Fourier Dönüşümlü Kızılötesi FTIR Spektroskopisi, Taramalı Elektron Mikroskobu SEM  Enerji Saçılımlı X-Işını Spektroskopisi EDS ve optik mikroskopi teknikleriyle gerçekleştirilmiştir.
