Polarographic Behaviour of Rhodamine 6G Ⅱ Adsorptive Complex Wave of Antimony(Ⅲ)

摘要: 研究了銻與碘化鉀和羅丹明類染料在HAC-NaAc緩沖溶液(pH5.6)中的極譜行為,探討了反應機理,提出痕量銻的測定方法。線性范圍在銻濃度為0.5~2000ng/ml,檢出限0.33ng/ml。Abstract: The electrochemical behaviour and the current property of antimony based on the formation of ion-associate complexes of Sb(Ⅲ) with iodide and rhodamine basic dyes are investigated in HAc-NaAc buffer solution (pH 5.6).The mechanism of related reactions is discussed.A new simple,sensitive and selective oscillopolarographic method is established for the determination of trace antimony. The detection limit was 0.33 ng/ml.
