| Abstract: | The content of cystine in cystine product from hair was determined indirectly by measuring the content of sulphur in it by ICP-AES.Samples were dissolved in 2%HNO3 solution and measured using oxygen as additional gas.This method has good repeatability and good linear relationship.The relative coefficient was above 0.9999 at the range of 0.13—853.36mg·L-1.The recovery was 95.0%—111.5% and RSD was less than 1.3%.This method was simple,rapid accurate and sensitive. |
