Eu(III)-TTA 착물계의 형광감소 현상에 의한 옥살산 이온의 정량

초록

The determination of oxalate ion has been investigated using the fluorimetric quenching of Eu(III)-TTA complex. The decrease in the fluorescence intensity of the Eu(III)-TTA complex was a linear function of the oxalate ion concentration. The linear range was 1ㅌ10-5-10ㅌ10-5 M when the concentration of Eu(III) and TTA were 1x10-5 and 1x10-5 M,respectively.
