硝酸银标准溶液是药房快检中最常用的一种标准溶液。但标定其准确浓度时,对所用基准物质氯化钠的干燥处理,按文献介绍的定温定时干燥(110℃、130℃;或高温烘烤(270℃)、灼烧(500-600℃)至恒重均较费时。我们在标定硝酸银溶液的准确浓度时,摸索一种炒制氯化钠法,经实验观察,除吸潮效果较好外,还具有简便、快速、经济等优点,适用于医院药房快检。现介绍如下。一.炒制方法取基准氯化钠(AR或GR纯)适量,研
Silver nitrate standard solution is the most commonly used standard pharmacy solution. However, the calibration of its exact concentration, the reference material used in the drying of sodium chloride, according to the literature fixed temperature drying time (110 ℃, 130 ℃; or high temperature baking (270 ℃), burning (500-600 ℃) to Constant weight are more time-consuming. We in the calibration of the exact concentration of silver nitrate solution, to explore a method of frying sodium chloride, the experimental observation, in addition to good moisture absorption effect, but also has the advantages of simplicity, speed, economy, for Pharmacy in the hospital fast test are as follows .A frying method to take the benchmark sodium chloride (AR or GR pure) amount of research
