TUNÇBiLEK TERMiK SANTRALI UÇUCU KULUNDEN METALLERiN LİÇ EDiLEBiLiRLiGi VE Ni KAZANIMI

Bu caltsmada, yanma islemi strasinda elektrostatik filtrelerdetoplanan Tuncbilek termik santralt ucucu kulu icerisindeki metaliyonlarintn (Ni, Cd, Mn) potansiyel hareketliliginin belirlenmesiamaclanmtstir. Caltsmantn ilk bolumunde farklt pH degerlerinde gerceklestirilenkolon lici deneyleri sonunda, pli'taki azalmanin ucucukulden metal iyonlartrun cozundurulmesinde etkili oldugu tespit edilmistir.Ni ve Cd, cozundurme isleminin ilk 20 dakikast icerisinde htzltbir sekilde katt partikulden uzaklasirken, matriks elementi olan Mnicin cozunme htzt daha yavasttr. Caltsmantn ikinci ktsminda kulpartikul icerisinde farkli kimyasal bilesimlerde bulunan Ni'in kazantmticin uc fir; yontemi uygulanmtsttr. Lie testleri sonrasi Ni %72 ral1~dtmanla kati partikulden cozeltiye gecirilebilmektedir.
