| Abstract: | It is found that the presence of Eu ( I ) has a remarkable quenching effect on the chemilumi-nescence reaction system of lun\inol-H_2O_2-Cr(. I ). A FlA-chemiluminescence method for the determination of europium is established based on this phenomenon. A linear relationship for Eu( I ) in the concentration range of 1.0 ?10~(-7)~1.0?10~(-1)mol ?L~(-1) is found, with a relative coefficient of 0. 9983 and a detection limit of 2?0~(-1)mol |
