中国药典2010年版:焦锑酸钾试液 取焦锑酸钾2g,在85ml热水中溶解,迅速冷却,加入氢氧化钾溶液(3→20)10ml;放置24小时,滤过,加水稀释至100ml,即得。与 USP32一致(Potassium Pyroantimonate TS —Dissolve 2 g of potassium pyroantimonate in 85 mL of hot water. Cool quickly, and add 10 mL of a solution of potassium hydroxide (3 in 20). Allow to stand for 24 hours, filter, and dilute with water to 100 mL. ) 但是USP33为Potassium Pyroantimonate TS —Dissolve 2 g of potassium pyroantimonate in 85 mL of hot water. Cool quickly, and add a solution containing 2.5 g of potassium hydroxide in 50 mL of water and 1 mL of sodium hydroxide solution (8.5 in 100). Allow to stand for 24 hours, filter, and dilute with water to 150 mL. 请教各位高手:焦锑酸钾试液用来做钠盐鉴别,那为什么在试液配制中要加入氢氧化钠溶液?
