Abstract:Ultraviolet-visible spectrophotometry was used to determinate the content of bromate in mineral water and drinking water.The effect of reaction time,dosage of hydrochloric acid,dosage of potassium iodide,working curve and recovery were studied,and the content of bromate in mineral water anddrinkingwater was testedinabsenceofthelightas 10.33 and 9.33 μg/L,respectively.The recovery of mineral water is 96.03%~105.59%,while the recovery of drinking water is 95.89%~96.12%.The precision and detection limit of this method are 0.36 and 0.108,respectively.
Keywords:Mineral water  Drinking water  Spectrophotometry  Bromate
