We demonstrate that electorogenerated chemiluminescence (ECL) of an organometallic Eu(III) complex, tris(dibenzoylmethane)phenanthroline europium(III), whose emission spectra is very sharp with the maximum wavelength of 612 nm, can be used as a light source for the detection of PO based on changing the absorbance of the ion associate of malachite green (MG) and phosphomolybdic acid. The ECL was also applied to measure the absorbance of MG. With the detection system we established, absorbance up to ∼1.6 with a change of ∼0.1 could be detected.
我们证明，有机金属铕（III）配合物三（二苯甲酰甲烷）菲咯啉铕（III）的电致化学发光（ECL）可作为检测磷酸根的光源，其发射光谱非常尖锐，最大波长为612nm，基于孔雀石绿（MG）与磷钼酸离子缔合物吸光度的变化来检测磷酸根。该ECL还用于测量MG的吸光度。利用我们建立的检测系统，可检测到吸光度变化约0.1时高达约1.6的吸光度。
