Abstract：A method for the determination of total sulfur in vitamin A was established using an energy-dispersive X-ray fluorescence spectrometer.The results showed that the sulfur content had good linearity in the concentration range of 0 to 3000 mg/kg,with a correlation coefficient greater than 0.999.Standard addition recovery and precision tests were conducted on actual samples,resul-ting in a recovery rate ranging from 97.3%to 99.1%and a precision RSD of 0.57%.The actual oper-ability was verified by analyzing 5 batches of actual samples.
