FERRO MOLİBDENİN ASİDİK ORTAMDA ÇÖZÜNME PARAMETRELERİNİN İNCELENMESİ

Year 2016, Volume: 4 Issue: 4, 235 - 240, 21.12.2016

Abstract

Bu araştırma çalışmasında; oksitleyici olarak HNO3 içeren H2SO4 çözeltisiyle ticari kalite ferro molibden içerisinden molibdenin ve demir çözeltiye alınması ve çözünme kinetiği araştırılmıştır. Çözümlendirme deneylerinde, çözücü miktarları, karıştırma hızı, reaksiyon süresi ve sıcaklık deney parametreleri olarak seçilmiştir. Sonuçlar, 2,5 g FeMo tozunun 70°C sıcaklığında, 4M H2SO4, 0,8 mL HNO3, 100 mL çözelti, 600 devir/dakika karıştırma hızı ve 360 dakika reaksiyon süresinde kullanıldığında Mo ve Fe in çözünme verimleri +%99 olarak elde edilmiştir. Ek olarak, Mo ve Fe in çözünme kinetiği reaksiyon mekanizması difüzyon kontrollü olduğu bulunmuş; Mo için 25,62kJ/mol; Fe için 19,51 kJ/mol olarak hesaplanmıştır.
