| Abstract: | In this paper,the ion selective electrode method was applied for determining I-in NaCl-riched oilfield water with recommendation.A good linearity of the standard curve was observed in the range from 7.49×10-6 mol/L to1.00 mol/L with correction coefficient of 0.9995.The mean recovery of the method is 98.8% with the RSD of 1.0%(n=6).The method is proven to be simple,rapid and exact for determination of I-in oilfield water. |
