dc.description.abstractIn 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 Pak's structure by hydropulping process and polyethylene was separated from Tetra Pak's 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 Al(OH)3 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.
dc.description.abstractBu çalismada atik Tetra Pak ambalajlarindan hidrometalurjik yöntem kullanilarak Al2O3 elde edilmesi amaçlanmistir. Tetra Pak geri dönüsümü, dünya çapinda giderek daha fazla arastirilan bir konu haline gelmistir. Tetra Pak ambalajlarinin yapisini olusturan selüloz, polietilen ve alüminyum, geri dönüstürülerek yeniden kullanilabilen hammaddelerdir. Tetra Pak’in yapisindan selüloz hidropulping prosesi ile, polietilen ise HCl ile liç prosesiyle ayristirilmis ve deneysel çalismalarda bu prosesler için optimum parametreler arastirilmistir. Yapidaki alüminyum, 0,1750 M ve 0,1312 M asit konsantrasyonuyla yapilan deneylerde %100 verimle çözünmüstür. Asit çözeltisinde çözünen alüminyum, AlCl3 fazi olarak elde edilmis ve %100 stokiyometrik NaOH ilavesiyle Al(OH)3 olarak çöktürülmüstür. Bu çökeltiler Al2O3 yapisi elde etmek için 950 °C'de 1 saat kalsine edilmistir. Deneysel çalismalarda kullanilan malzemelerin ve bu deneyler sonucunda elde edilen ürünlerin analizleri Atomik Absorbsiyon Spektroskopisi (AAS), Fourier Dönüsümlü Kizilötesi (FTIR) Spektroskopisi, Taramali Elektron Mikroskobu (SEM) / Enerji Saçilimli X-Isini Spektroskopisi (EDS) ve optik mikroskopi teknikleriyle gerçeklestirilmistir.
