| Abstract: | Using 95% ethanol as the solvent, we directly determined zinc in polymerized rosin by flame atomic absorption spectrometry. The recovery rate is from 100 to 103 percent. The relative standard deviation (RSD) of the determination is between 1.1-4.1%. The sensitivity is high and the characteristic concentration reaches 0.0077 microg x mL(-1)/1%. The method is quite significant in forestry chemical works with its simplicity and efficiency. |
