摘　　要：以金电极为工作电极,考察了温度对Ru(bpy)_3^(2+)-苦参碱测定体系电致化学发光行为的影响,结果表明,温度对Ru(bpy)_3^(2+)-苦参碱体系电化学发光行为有显著影响。0~75℃,体系电化学电流强度随温度升高而增强,电化学发光强度值则随温度升高先增后减。在最优条件下,苦参碱在0.1~100mmol/L范围内线性关系良好。回收率为101.1%,RSD为1.58%。The influence of temperature on the electrochemiluminescence （ECL） behavior of Ru（bpy）32＋- matrine system was studied on the gold electrode. The results showed that the temperature had a significant impact on ECL behavior of Ru （bpy） 3^2＋-matrine system. The electrochemical current was enhanced with the increase of temperature from 0 ℃ to 75℃, however the ECL intensity increased before 25 ℃ and then decreased. Under the optimum experimental conditions, it was linear for matrine in the range of 0.1--100 gmol/L. The recovery was 101.1%, with RSD of 1.58%.
