盐酸吗啉双胍片的含量测定,一些药品标准均采用非水滴定法。本文根据盐酸吗啉双胍的水溶液在237±1nm 波长处有最大吸收的特性,采用紫外分光光度法测定其含量,得到满意结果。一、仪器与试药UV-260型紫外可见分光光度计(日本岛津)。WFZ-800D_3A 型紫外可见分光光度计(北京第二光学仪器厂)。盐酸吗啉双胍原料及盐酸吗啉双胍片均由本市某药厂提供。二、吸收光谱的测定
Hydrochloride morpholine biguanidine tablets content determination, some drug standards are used non-water titration method. In this paper, according to the maximum absorption of morpholine biguanide aqueous solution at the wavelength of 237 ± 1nm, its content was determined by UV spectrophotometry, and satisfactory results were obtained. First, equipment and reagents UV-260 UV-visible spectrophotometer (Shimadzu). WFZ-800D_3A UV-visible spectrophotometer (Beijing Second Optical Instrument Factory). Morpholine hydrochloride and morphine biguanide hydrochloride tablets are provided by the city of a pharmaceutical company. Second, the determination of absorption spectra
