摘要:

An oscillopolarographic titration method for the determination of norfloxacin in materials and capsules is described in this paper. The norfloxacin is precipitated as NOR-TPB. Filtrates were titrated with thallous sulfate in an alkaline solution. The recoveries ranged from 99.10% to 100.53% by the use of a standard addition. Experiments showed that the proposed method gave the same results as the approach using nonaqueous titration as USP and CSP.
