【Abstract】 Sodium dodecylbenzene sulfonate(SDBS) in environmental water can be determined by derivative spectrophotometric method. The effects of phenol and nonyl phenol polyoxyethylene ether were studied. The appropriate condition of determination was chosen. SDBS content was determined with a linear range of (0-20)mg·L -1 and recovery of 97 2%-102 3%.更多还原
