摘要
Abstract
In the process of determining the copper content in copper ore,iodometric method is a commonly used method.However,this method is prone to a series of phenomena such as excessive volatilization of iodine or precipitation of copper iodide during application,which ultimately leads to certain errors in experimental results.But through relevant research,it has been found that if the iodometric determination can be completed under the condition of potassium thiocyanate,the solubility of copper iodide precipitation can be effectively enhanced,and potassium thiocyanate can also form a very stable complex with iodine,which can displace the adsorbed iodine molecules from the precipitation surface,effectively improving the accuracy of the measurement results and making the operation very simple.Therefore,in this article,the focus will be on how to efficiently determine the copper content in copper ore using the iodometric method,hoping to provide some assistance to relevant personnel.关键词
