| Abstract: | In this paper, the test method （sodium hypochlorite - iodimetry） of bromide ion in liquid waste containing bromine is discussed. The test methodg practicability is studied by means parallel determination and standard recovery test. The experimental results show that, using the method of sodium hypochlorite - iodine of bromine liquid standard addition recovery was 98. 1% - 101.7%, which falls in the scope of volumetric test method 95% - 105%. As a result, it is applicable for the of bromide ion in liquid waste containing bromine. |
