DETERMINATION OF TITANIUM IN ZINC ASH BY FAAS AFTER DIGESTED USING ULTRASOUND-ASSISTED EXTRACTION

Öz

Bu çalışmada, alevli atomik absorpsiyon (FAAS) kullanılarak galvaniz fabrikalarından alınan atık kül örneklerindeki Ti (titanyum) miktarının belirlenmesi amaçlanmıştır. Çeşitli galvanizleme sac veya boru proseslerinden elde edilen çinko külünün çözünürleştirilmesi için ses destekli ekstraksiyon kullanılarak çeşitli zaman periyotları ve farklı çözücü karışımları incelenmiştir. Galvanizli atıkta Ti metali için en iyi çözücü karışımları sırasıyla, HCl:HNO3:H2O2 (1:3:2) > HCl > HNO3:HCl (1:3) > HNO3 > HNO3:H2SO4 (3:1) > HNO3:H2SO4 (1:1) > HNO3:H2SO4 (3:2) > HNO3:H2SO4 (2:1) olarak bulunmuştur.

Determination of Titanium in Zinc ash by FAAS After Digested using Ultrasound-Assisted Extraction

Öz

In this study, it is aimed to determine the amount of Ti (titanium) in waste ash samples taken from galvanizing factories by using flame atomic absorption (FAAS). Various time periods and different solvent mixtures were examined by using ultrasound-assisted extraction for digestion of zinch ash which taken from various processes of galvanizing metal sheet or pipe. The best solvent mixtures for Ti metal in galvanized waste was found HCl:HNO3:H2O2 (1:3:2) > HCl > HNO3:HCl (1:3) > HNO3 > HNO3:H2SO4 (3:1) > HNO3:H2SO4 (1:1) > HNO3:H2SO4 (3:2) > HNO3:H2SO4 (2:1), respectively.
