| 摘 要： | 用四苯硼钠示波极谱滴定法测定了氢溴酸后马托品。在pH5.3的HAc—NaAc缓冲溶液中,以过量定量之四苯硼钠沉淀后马托品,然后用硫酸亚铊标准溶液回滴剩余的四苯硼钠,以四苯硼钠在示波极谱图上切口的消失指示终点。用此法测定了氢溴酸后马托品原料药和眼膏制剂。回收率分别为99.51%和98.76%。 |
| 关 键 词： | 示波极谱滴定 氢溴酸 后马托品 |

| Abstract: | This peper deals withthe method of oscillopolarographic titrationof Homatropine Hydrobromide with Na-tetraphenylborate (Na-TPB) solution. Anexcess amount of standard solution ofNa-TPB is added to an acetate buffersolution (pH=5.3) containing the sampleto precipitate homatroping quantitatively.Adjust the solution to alkaline and titra-te the excess NaTPB With standard thall-ous sulfate solution. Homatropine Hydro-bromide and its ophthalmic ointment wasdetermined. Their recovery are 99.51%and 98.76%. |
