摘要
在EDTA存在下,于氨性介质中,用硫酸铍作载体,使锡与主体铋分离,在0 5mol/L硫酸溶液中,用苯芴酮-十六烷基三甲胺光度法测定锡量。测定范围:5×10-5%～5×10-4%,相对标准偏差为1 94%～2 38%。
In the presence of EDTA,Tin is separated from base metal Bismuth using Beryllium Sulphate as carrier in ammoniac solution.In 0.5 mol/L Sulphuric Aicd, Tin is determinated with Plenyfuorone-cetyltrimetnylammonium-bromides spectrophotometric method.The range of measurement is 5×10~-5%～5×10~-4%, The RSD was found between 1.94% to 2.38%.
