由于没有人愿意参与,我自己翻译一下,欢迎大家指正:
除另有规定外,取各品种项下规定量的供试品,加水溶解使成25ml(溶液如显碱性,可滴加硝酸使成中性),再加稀硝酸10ml;溶液如不澄清,应滤过;置50ml纳氏比色管中,加水使成约40ml,摇匀,即得供试溶液。
Test solution: unless otherwise specified, weigh specified quantity of test sample in the individual monograph, dissolve and dilute to 25ml with water (if the solution is alkaline, dropwise add nitric acid to neutral), add 10ml of dilute nitric acid, filter if the solution is not clear. Transfer this solution to a 50-ml nessler tube, dilute to 40ml with water, mix.
