摘要
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。
Introduced a method for testing the acetate acid content of the dialysis fluid. Method：Testing the acetate acid content of the dialysis fluid by the first-derivative spectroscopy. Wavelength scanning between 190 - 300nm.Results：The linear correlation of acetate was 9.8 ~ 58.6mmol/L with correlation coefficient of 0.9998.The average recovery was 99.9%,RSD%=0.80% （n=3）.Conclusions：The results showed that the method is accurate,simple and rapid for analysis of acetate in dialysate.
