| Abstract: | A method for the determination of abietic acid and dehydroabietic acid in rosin is proposed by derivatve spectrophotometry. The fourth derivative spectrophiotometry was used for the simultaneous determination of abietic acid and dehydroabietic aeid in different kinds of rosins with satisfactory results. The method operats simply with high sensitivity. The relative standard deviation of 0. 17%(n=11), the abietic acid recovery of 99. 17%, the dehydroabietic acid recovery of 69. 27% were found. |
