氯化氨基汞及硫酸镁的鉴别,按药典法操作[参阅中国药典1977年版664页(1)法及附录36页(1)法],结果很不理想,有的甚至不呈现正反应。如氯化氨基汞按药典法取量,(1)检品在试剂中不能全溶,(2)加热无红色硫化汞沉淀产生,致使反应呈阴性。硫酸镁按药典法鉴别,灵敏度极低,且反应时间、检品和试剂用量等均较难掌握,控制不当易导致阴性结果。经改变反应条件、试剂及检品用量后方得出较满意的结果。现将改进方法分述如下。一、操作
Ammonium chloride and magnesium sulfate identification, according to the Pharmacopoeia Act [see Chinese Pharmacopoeia 1977 edition 664 (1) Act and Appendix 36 (1) method], the result is very unsatisfactory, and some do not even appear positive response. For example, the amount of aminomercuric chloride should be taken according to the method of Pharmacopoeia. (1) The sample should not be completely dissolved in the reagent, and (2) the product should be heated without any precipitation of red mercuric sulfide, resulting in a negative reaction. Magnesium sulfate identification by the Pharmacopoeia method, the sensitivity is very low, and the reaction time, the amount of seized goods and reagents are more difficult to grasp, improper control can lead to negative results. After changing the reaction conditions, the amount of reagents and seized after the rest of the more satisfactory results. Now improve the method described below. First, the operation
