摘要
分析了各种分离条件和检测条件对发光强度的影响;并在实验优化的条件下,对浓度在1.0×10-6~1.0×10-4mol.L-1范围内的利多卡因进行检测,发现发光强度与其浓度呈良好的线性关系,线性回归方程为ΔI=11.74c+34.696(c:μmol.L-1),线性相关系数R2=0.991 7。方法的检出限为1.1×10-7mol.L-1,对1.0×10-5mol.L-1的利多卡因溶液进行10次测量,相对标准偏差为1.12%。
The paper analyses the influence of various separation and detection conditions on luminous intensity and,when lidocaine is detected in the optimized experiment condition within the density between 1.0×10-6~1.0×10-4 mol·L-1,it is discovered that luminous intensity are in good linear relationship with its densityand equation of linear regression is △=11.74c+34.696(c:μmol·L-1) and the linear related coefficient R2=0.9917.The detection limit of the method is 1.1×10-7 mol·L-1 and through 10 detections of lidocaine of 1.0×10-5 mol·L-1 the relative standard deviation is 1.12%.
