摘要
ＤＣＳ－偶氮胂光度法测定钛酸锶烧结物中游离的氧化锶胡浩，周宏实江苏海安磷肥厂２２６６００ＤＣＳ－偶氮肿［２－（２－胂酸基苯偶氮）－７－（２，６－二氯－４－磺酸基苯偶氮）－１，８－二羟基－３，６－二磺酸萘］属双偶氮变色酸类显色剂，主要用于稀土元素的高灵...
trontium reacts with DCS-arsenazo in an ammonia and ammonium chloride buffer mediumto form a 1:2 stable complex with maximum absorption at 620nm,the molor absorptivity being5.8×10￣4L·mol￣-1·cm￣-1. Beer′s law is obeyed in the range of 0～0.48μg/ml Sr. The methodhas been applied to the analysis of strontium titanate sinters with satisfaction.
