原子吸收光谱法测定复方氯化钠注射液中氯化钙含量
Determination of Calcium Chloride in Compound Sodium Chloride Injection by Atomic Absorption Spectrometry
摘要
Abstract
A method was established to determine the content of calcium chloride in compound sodium chloride injection .By atom-ic absorption spectrometry , the content of calcium chloride in compound sodium chloride injection was determined under the condition as follows:detection wavelength was 422.7 nm,the flame tape was air/acetylene(13.5∶2.0),the lamp current was 10 mA,slit width was 0.5 nm.Good linear relationship of concentration and absorption of Ca 2+was within the range of 1μg/mL-9μg/mL, the recovery rate range from 98.42%to 100.93%, detectability was 0.008206μg/mL,the RSD between results obtained from official method and ones obtained from comparative method is 1.21%.This method has good specificity, stability, reproducibility, and is accurate for de-tecting the content of Ca 2+,and can be supplementary method to official one .The concentration of calcium chloride in compound sodi-um chloride injection is between 0.0329296%g/mL and 0.0340398%g/mL, which meets the required quality standards .关键词
