高鉻鋼中锆的測定微量锆的比色法試剂一般有茜素磺酸鈉,邻苯二酚紫,檞皮素,Spadns,四羟蒽醌等(1～6),Young曾对各方法进行了比較,认为邻苯二酚紫較好。茜素磺酸鈉快速測定鋼铁中锆的方法要求的酸度范圍較严(pH0.6～1.5),干扰元素較多,必需先用汞阴极电解分去大量铁、錳、镍、鉻等元素,然后利用剩余之铁,錳,共沉淀锆,經过二道分离手續。若松茂雄介紹了以四羟蒽醌快速測定鋼中錯的方法,干扰元素如铁、銅等加入EDTA以隐蔽,調节pH至5,
High chrome steel zirconium determination of trace zirconium colorimetric reagents are generally sodium alizarin sulfonate, pyrochlore purple, dermatan, Spadns, four hydroxyanthraquinone (1 ~ 6), Young had each Methods were compared, that catechol purple is better. Alizarin sulfonate rapid determination of zirconium in steel requires a more stringent range of acidity (pH0.6 ~ 1.5), more interference elements, you must first use mercury cathode electrolytic separation of a large amount of iron, manganese, nickel, chromium and other elements, Then use the remaining iron, manganese, coprecipitated zirconium, after two separate procedures. Wakabayashi Matsushita introduced tetrakis anthraquinone rapid determination of steel in the wrong method, interference elements such as iron, copper and so on by adding EDTA to conceal, adjust the pH to 5,
