Abstract

The oxidation of aqueous cyanides in packed columns has been studied. The experiment was performed in three différent temperatures on inert packing at co- and counter-current conditions. In addition to this, experiments made on room temperature were repeated in the presence of catalyst. After reaching to steady state in each case, cyanide concentrations of liquid samples taken from the column outlet were titrimetrically determined. Oxidation yields were calculated by comparing these values to the initial ones. As a result, it was observed that the oxidation yield was increased with increasing of temperature and addition of catalyst.

Özet

Sulardaki siyanürün dolgulu kolonlarda oksidasyonu araştırıldı. Deneyler paralel ve ters akış şartlarında, inert dolgulu sistemde, üç farklı sıcaklıkta gerçekleştirildi, ilave olarak, oda sıcaklığında yapılan deneyler katalitik sistemde tekrarlandı. Herbir farklı durumda yatışkın hale erişildikten sonra kolon çıkışından alınan sıvı numunelerdeki siyanür konsantrasyonları titrirnetrik olarak belirlendi. Bu değerler başlangıç konsantrasyonları ile karşılaştırılarak % oksidasyon verimlerine geçildi. Sonuçta gerek sıcaklık artışının, gerekse katalizör ilavesinin oksidasyon veriminde artışa sebep olduğu görüldü.
