<span style="font-size:12.0pt;font-family: " times="" new="" roman";mso-fareast-font-family:"times="" roman";mso-ansi-language:="" en-in;mso-fareast-language:en-in;mso-bidi-language:ar-sa"="" lang="EN-IN">A polarographic method of determining yttrium is described. The method is based on the changes in the polarographic behaviour of the <i style="mso-bidi-font-style:normal">o</i>-hydroxyazo dye, Arsenazo- I, in presence of yttrium. It<span style="font-size:12.0pt;font-family:Arial;mso-fareast-font-family:" times="" new="" roman";="" mso-ansi-language:en-in;mso-fareast-language:en-in;mso-bidi-language:ar-sa"="" lang="EN-IN"> <span style="font-size:12.0pt;font-family:" times="" new="" roman";mso-fareast-font-family:="" "times="" roman";mso-ansi-language:en-in;mso-fareast-language:en-in;="" mso-bidi-language:ar-sa"="" lang="EN-IN">is demonstrated that the method could be applied for determination of yttrium in the superconducting oxide YBa₂CU₃O_y(y=6.5-7.0).</span></span></span>
