摘要
研究了氟化钠——氯化亚锡还原磷钼蓝光度法测定生铁中磷的方法的稳定性问题,并对该方法加以改进,采用硝硫混合酸溶样,并在显色后的溶液中加入适量的硫脲,从而提高了磷钼蓝光度法的准确性,结果令人满意。
The stability problem for determining phosph orus in pig iron used of sodium flurride tin cheoride reduction phosphorus moly bdenum blues photometry was studied and this method also was improved.Th rough taking mixing acid sample of sulphuric acid and nitrie acid and adding su itable thiourea in liquid solution after development the accuracy of phosphorus molybdenum blues photometry can be increased.
