Description
Summary:In this paper results of copper removal in ordinario and ethyl alcohol by cementation using an iron rod as a sacrifice anode are presented. Experiments were performed in ordinario containing copper without controlling pH and in an acetate buffer. Concentration before and after cementation were determined by atomic absorption spectroscopy. The highest removal efficiency of Cu (II) in ethyl alcohol and ordinario without buffer occurs at pHs of 4.8 and 3.3 respectively, with 49% removal in both cases. On the other hand, the highest removal percentage of Cu(II) in ethyl alcohol and ordinario at buffered conditions and pHs of 4.9 and 3.0 are 52.1 and 61.1% respectively, the major removal efficiency appears at more acidic pHs because iron has a major facility to oxidize in acidic pH.
