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.

Anahtar Kelimeler

Tunçbilek Termik Santrali, uçucu kül, liç, Ni kazanımı
