| Abstract: | A simple ultraviolet-spectrophotometric method was developed for the Determination of bromate in water samples.Bromate reacts with iodide in acidic media to produce tri-iodide which has a UV absorbance at 288 nm and thus can be monitored spectrophotometrically.The recovery of bromate Determination by UV spectrophotometry was 98%~102%,and the relative standard deviation was 1.7%(n=9).The calibration equation for bromate analysis has a good linearity with regression coefficient of 0.9991.The detection of limit for bromate was 4.0 μg/L,showing that the method can meet the testing requirement. |
