Key Findings & Data:Caltsmantn ilk bolumunde farklt pH degerlerinde gerceklestirilen kolon lici deneyleri sonunda, pli'taki azalmanin ucucu kulden metal iyonlartrun cozundurulmesinde etkili oldugu tespit edilmistir.
💡
Conclusion & Impact:Lie testleri sonrasi Ni %72 ral1~ dtmanla kati partikulden cozeltiye gecirilebilmektedir.
Bu caltsmada, yanma islemi strasinda elektrostatik filtrelerde toplanan Tuncbilek termik santralt ucucu kulu icerisindeki metal iyonlarintn (Ni, Cd, Mn) potansiyel hareketliliginin belirlenmesi amaclanmtstir. Caltsmantn ilk bolumunde farklt pH degerlerinde gerceklestirilen kolon lici deneyleri sonunda, pli'taki azalmanin ucucu kulden metal iyonlartrun cozundurulmesinde etkili oldugu tespit edilmistir. Ni ve Cd, cozundurme isleminin ilk 20 dakikast icerisinde htzlt bir sekilde katt partikulden uzaklasirken, matriks elementi olan Mn icin cozunme htzt daha yavasttr. Caltsmantn ikinci ktsminda kul partikul icerisinde farkli kimyasal bilesimlerde bulunan Ni'in kazantmt icin uc fir; yontemi uygulanmtsttr. Lie testleri sonrasi Ni %72 ral1~ dtmanla kati partikulden cozeltiye gecirilebilmektedir.
