摘　　要： 固体表面化学发光法测定微量样品中钴的研究章竹君，杨维平，吕九如（陕西师范大学化学系，西安，７１００６２）关键词固体表面发光，化学发光，钴，微量技术固体表面化学发光法（ＳＳＣＬ）已用于多种无机离子及生物活性物质的测定［１］，该法结合多种分离技术能有效地... A solid surface chemiluminescence method using the filter paper with anti-permeate barrier as a solid substrate to measure cobalt based on luminol-H2O2-Co(Ⅱ)system is described. The chemiluminescence characteristics of cobalt(Ⅱ) on the solid surface is investigated. The linear range for cobalt is 0.1 1000 ng. The detection limit is 8 pg/spot, and the relative standard deviation for 0. 1 ng cobalt is 7.2%(n=11). The present method has been successfully applied to the microanalysis of cobalt in the monomineral and steel.
