Title: Study on luminol-H_2O_2-Fe(II) chemiluminescence system and its application
Abstract: Based on the function of enhancing stability,sensitivity and dissolvability of microemulsion,the chemiluminescence reaction in the system of microemulsion-luminol-H2O2-Fe(Ⅱ)was investigated.The method can be used to determine effectively Fe(Ⅱ)in the range of 1×10-6 to 1×10-4 g/L with the detection limit of 1.20×10-7 g/L.The relative standard deviation is 1.33% for determination of 1×10-6 g/L Fe(Ⅱ)(n=11).Moreover,the interference from the majority elements can be eliminated using EDTA as masking agent.The method is successfully applied to determine Fe(Ⅱ)in ore samples with the recovery of 96%-107%.
