| Abstract: | The pH indicator absorbance ratio method was applied to the quantitative determination of ethambutole hydrochloride. The determination procedure is as follows:Alizarin yellow R and standard solution of 0.1mol/L NaOH were used; the absorbance values at 374nm and 500nm were measured. The contents of three batches of ethambutole hydrochloride were 99.5%, 99.4% and 99.6%, respectively, which were the same as in the harmacopeia. |
