| Abstract: | Critical micelle concentration（CMC） of sodium dodecyl sulfate（SDS） in aqueous solution of iodine and I-3 solution was determined,and the effects of two salt,sodium sulfate and potassium chloride on the CMC of SDS in the aqueous solution of iodine in different concentrations of iodine were also discussed.The CMCs of SDS obtained in two different system are different by spectrophotometry.Sodium sulfate on the impact of the surface activity of SDS is greater than potassium chloride in I-3 solution,,and with the increasing concentration of iodine,the CMC of SDS shows the trend of increasing in the aqueous solution of iodine. |
