| Abstract: | The chlorine content in the sample,which was pretreated by the oxygen bottle combustion method,was determined by the turbidimetric method on an UV spectrophotometer.450 nm was selected as the primary wavelength.The method showed a good linearity and repetition in the range of 0.8～8.0 μg/mL with a correlation coefficient of 0.999 88.The recovery was 91.1%～118.6%.The method is usable to determine the chlorine content in organic compounds. |
| Keywords: | turbidimetry chlorine content organic compounds spectrophometry |
