Özet
Bu çalışmada, ileri oksidasyon yöntemi olan katalitik oksidasyon yöntemi ile sulardan doğal organik madde giderimi incelendi. Doğal organik maddelerin klorla reaksiyonundan oluşan THM öncülerinin sudan uzaklaştırılması katalitik oksidasyon işleminde oluşan hidroksil radikalleri ile sağlandı. Çalışmalar üç bölümde yürütüldü. Birinci bölümde saf suda hidrojen peroksitin demir kaplı pomza katalizörlüğünde ayrışması, ikinci bölümde hümik asitli ortamda demir kaplı pomza katalizörlüğünde hidrojen peroksitin ayrışması, üçüncü bölümde ise demir kaplı pomza katalizörlüğünde hidrojen peroksitle hümik asit giderimi araştırıldı. Hümik asit giderimi, suyun Toplam Organik Karbon içeriği ve Trihalometan Oluşum Potansiyelindeki (THMOP) değişimler ile izlendi. Yapılan çalışmalar sonucunda, saf suda ve hümik asitli ortamda demir kaplı pomza katalizörlüğünde hidrojen peroksitin ayrıştığı gözlendi.
In this study, removal of natural organic matter from water was investigated by catalytic oxidation process which is an advanced oxidation process. Removal of THM precursors which is formed by the reaction of natural organic matters with chloride, was performed with the hydroxyl radicals that is produced in catalytic oxidation process. The studies were carried out in three sections. In the first section, decomposition of hydrogen peroxide in pure water with the catalysis of iron coated pumice, in the second section decomposition of hydrogen peroxide in the humic acid medium with the catalysis of iron coated pumice, in the third section removal of humic acid by hydrogen peroxide with the catalysis of iron coated pumice. Removal of humic acid and total organic carbon content in water, and the variation of formation potentials of THM was followed. At the end of this study it was observed that the decompositin of hydrogen peroxide in the pure water and in the humic acid medium with the catalysis of iron coated pumice.
