输血用枸橼酸钠注射液(含氯化钠、枸橼酸钠)和血液保养液(含枸橼酸、枸橼酸钠、葡萄糖)的含量测定,大多数医院采用以黄橙Ⅳ为指示剂的中和法,此法终点难以观察。笔者参考有关文献试验了络合法,并做了回收率试验。实验结果表明:具有操作简便快速,终点可靠,滴定不易过量等优点。测定方法精密量取输血用枸橼酸钠注射液10ml(或血液 Transfusion with sodium citrate injection (including sodium chloride, sodium citrate) and blood maintenance solution (containing citric acid, sodium citrate, glucose) content determination, most hospitals using yellow orange IV as an indicator Neutralization of agents, the end of this method is difficult to observe. The author tests the complex law with reference to the literature, and made a recovery test. Experimental results show that: with simple and quick operation, reliable end, titration is not easy to overdose and so on. Determination of precise amount of blood taken with sodium citrate injection 10ml (or blood
