A precise and accurate gravimetric procedure was developed for the determination of chlorhexidine diacetate, digluconate, or dihydrochloride. Sodium tetraphenylborate solution was the precipitant in an acidic medium (pH 1). Tablets containing both chlorhexidine diacetate and benzocaine also were assayed.
开发了一种精确准确的重量法，用于测定醋酸氯己定、葡萄糖酸氯己定或盐酸氯己定。四苯硼钠溶液在酸性介质（pH 1）中作为沉淀剂。还对含有醋酸氯己定和苯佐卡因的片剂进行了测定。
