摘要
目的:建立院内制药用水中总有机碳(TOC)含量测定方法。方法:采用高温催化燃烧氧化法对不同批次的水样TOC进行检测分析。结果:总有机碳在0.024~10.0 mg·L^(-1)范围内呈现较好的线性关系,r=0.999 8,平均回收率97.37%(RSD=1.30%,n=9)。水样TOC含量符合纯化水《国家药典》标准。结论:该方法精密度高,稳定性好,可应用于源水,纯化水中总有机碳的测定。
Objective： To establish a quantitative determination method for total organic carbon （TOC） in medically used water. Methods： The method of heating oxidization was used to determine TOC. Results： TOC had a good linearity within the range of 0. 024-10.0 mg·L^-1 （ r = 0.999 8 ） , and the average recovery was 97.37 % （ RSD = 1.30%, n = 9 ）. TOC in medically used water was accorded with the standard of Chinese pharmacopeia. Conclusion： The method is accurate and stable, and can be used in the determi- nation of TOC in source water and pure water.
