Abstract

Abstract:

In the production process of lithium carbonate and the final product，the doping of trace magnesium will directly affect the product quality of lithium carbonate and the processing and application of downstream products，and the rapid detection of trace magnesium in high-purity lithium carbonate is still a difficulty.In this study，a method for detecting trace amounts of magnesium in lithium carbonate using a water-soluble fluorescent probe was proposed.The highly water-soluble tris（hydroxy） methyl aminomethane was used to modify 2-（2-hydroxyphenyl） benzoxazole.Water-soluble Mg²⁺ fluorescent probe A with high sensitivity and selectivity was constructed.This method could realize the rapid fluorescence detection of Mg²⁺ in lithium carbonate solution，and determine the quantitative relationship between the fluorescence signal intensity of probe A excited by Mg²⁺ and the concentration of Mg²⁺.The results showed that the detection limit of this method for trace magnesium was 2.014 9 μmol/L when the lithium carbonate containing magnesium impurities was detected under water-soluble conditions，and the correlation coefficient of the detection working curve reached 0.991 5，and the detection sensitivity was high.The detection time of magnesium was 3.666 s，which could realize the rapid quality inspection of Mg²⁺.
