| Abstract: | A reversed-phase high performance liquid chromatography-UV detection method has bee devel- oped for the determination of sodium dodecylbenzene sulfonate in wastewater.The effects of methanol con- tent.the type of electrolytes and their concentrations,pH and flow rate in the mobile phase on separation were investigated and optimized.Under the optimized conditions,the absorbance at 254 nm showed a line- ar relationship with the concentration of sodium dodecylbenzene sulfonate.The proposed method has been applied successfully to the analysis of sodium dodecylbenzene sulfonate in environmental wastewater samples. |
