摘　　要：文章基于变色酸显色的原理对钢铁中钛元素的含量进行测定,与既往的变色酸单独测定钛含量法不同,文章提出了通过使用硅锰磷联合测定法来对钛元素进行测定的方法,一次溶解试样即可完成硅锰磷钛等多种元素的测量,显著降低了测定成本并节约了测定时间。In this paper,the titanium content in steel is determined based on the principle of chromotropic acid.Different from the previous method of determining titanium content by chromotropic acid alone,this paper proposes to determine titanium by using Si-Mn-P combined determination method,which can complete the measurement of Si-Mn-P-Ti and other elements by dissolving the sample once,significantly reducing the measurement cost and saving the measurement time.
