摘　　要：基于溴离子选择电极的线性范围,溴质量分数在0.002%～0.2%时,应选择1μg/mL标准溶液系列并建立工作曲线,用于测定磷矿中微量溴的含量。该法便捷、快速,适用于磷矿中微量溴的测定。Based on the linear range of bromine ion selective electrode, 1 μ g/mL standard solution series should be selected and working curve created to determine the trace bromine content in phosphate rock with in the range of 0.002%-0.2% of the bromine mass fraction. The method is more convenient and faster to determine the trace bromine in phosphate rock.
