我們認为在葯房檢驗工作中要把增产节約搞好,首先是要从改进工作方法着手,其次是从廢物的利用方面去想办法。下述兩点是我們在增产节約中的一点体会: 1.在医院中,用于X光造影的25%碘化鈉注射液的数量是不少的,对于这种注射液的含量測定,我們过去是应用剩余滴定法去滴定的。該法是取样0.5g,加0.1NAgNO_3液40ml,,硝酸2ml,,搖匀后,加硫酸铁銨指示液lml,用0.1N NH_4CNS液將剩余的硝酸銀滴定,算出碘化鈉的含量。后来我們發現可用二氯熒光素为指示剂,以0.1N AgNO_3液去直接滴定时,便立即改用后者。該法取样0.25g,加水200ml,加二氯熒光素指示液 We think it is necessary to start the process of improving work efficiency and secondly to find ways to utilize the waste in the pharmacy inspection work. The following two points are our experience in increasing production and saving: 1. In the hospital, the amount of 25% sodium iodide injection used for X-ray is quite small. For the determination of the content of this injection, We used to use the remaining titration titration. The method is sampling 0.5g, plus 0.1NAgNO_3 solution 40ml ,, 2ml nitric acid, shake, add ammonium ferric sulfate indicator solution lml, with 0.1N NH_4CNS liquid remaining titration of silver nitrate, calculate the content of sodium iodide. Later, we found that the available dichlorofluorescein as an indicator to 0.1N AgNO_3 solution to the direct titration, they immediately switch to the latter. The law sampling 0.25g, add water 200ml, add dichloro fluorescein indicator solution
