Simultaneous Determination of Phenol and Resorcinol in Pharmaceutical Preparations by Kalman Filtering-Spectrophotometry

Abstract

Abstract: UVspectrophotometry based on Kalman filtering (KF) was applied to the simultaneous determination of phenol and resorcinol in synthetic mixtures and pharmaceutical preparations without preliminary separation. The average recoveries for phenol and resorcinol in their compound preparations are 100.86% and 98.76%, with standard deviations of 1.58% and 1.66%, respectively.

Key words: Kalman filtering-spectrophotometry, Simultaneous determination, Phenol, Resorcinol, Compound pharmaceutical preparation
