| Abstract: | A new method is proposed for the determination of stoichiometric composition of bismuth based superconductor by inductively coupled plasma atomic emission spectrometry(ICP-AES).The samples were dissolved in a mixture of hydrochloric and nitric acid.The spectral lines for elemental analysis were chosen as: Bi 223.061(151);Pb 216.999(155);Sr 346.446(97);Ca 315.887(106) and Cu 224.700(149).The optimal instrument working parameters were determined.The recoveries for the analyzed elements were in the range of 99.0%~102.0% and relative standard deviations were below 1.0%.The accuracy and precision of the method is good and can meet the requirements for routine analyisis of stoichiometric compositions of superconductor materials. |
