摘要
Abstract
China's titanium resources mainly come from ilmenite and rutile.Accurate quantification of the rutile titanium content is beneficial to resource evaluation and precise determination of the ore grade.In this paper,rutile titanium is screened out by using a mixture of sodium fluoride and hydrochloric acid.Then,the sample is dissolved with a mixture of sodium hydroxide and sodium peroxide in an alkaline environment,followed by water leaching and acidification with hydrochloric acid.The content of rutile titanium in zirconium-titanium sand is determined by Inductively Coupled Plasma Optical Emission Spectrometry(ICP-OES).During the experiment,the sample is completely decomposed through optimizing the dosage of sodium fluoride,the water bath time,and the alkaline dissolution time.The stability of the determination of the rutile titanium content is ensured by selecting appropriate extraction methods and analytical spectral lines,and the results are accurate and reliable.The detection limit of this method is 0.0051%,the quantification limit is 0.017%,the relative standard deviation(RSD)is between 2.59%and 4.72%,and the spiked recovery rate is between 98.2%and 103%.This provides a technical means for the rapid and efficient determination of rutile titanium.关键词
