| Abstract: | The micro chloride ion in benzene was determined by spectrophotometry. Benzene was extracted by secondary distillation water, the micro chloride ion in water layer was determined by sulfocyanide spectrophotometry. The regression equation was Y=0.001 3 C,correlation coefficient was 0. 996 2. The range of recovery was 93.3% -97.6% ,the RSD was 4.1%. |
