目的:建立一种测定血液透析用浓缩物中醋酸根含量的方法。方法:采用一阶导数光谱法测定血液透析用浓缩物中醋酸根的含量。波长扫描范围:190～300nm。结果:醋酸根线性范围是9.8～58.6mmol/L(r=0.9998),平均加样回收率为99.9%,RSD=0.80%(n=3)。结论:此方法操作简便,测定时间短,准确度高,浓缩物中其他离子对测定结果基本无影响。
Objective: To establish a method for determination of acetate content in hemodialysis concentrates. Methods: The first order derivative spectrometry was used to determine the acetate content in hemodialysis concentrates. Wavelength scanning range: 190 ~ 300nm. Results: The linear range of acetate was 9.8-58.6 mmol / L (r = 0.9998). The average recovery was 99.9% and the RSD was 0.80% (n = 3). Conclusion: This method is simple and easy to operate, the determination time is short and the accuracy is high. Other ions in the concentrate have no effect on the determination results.
