| Remarks： |
A reversed-phase ion-pair chromatography method with ammonium tetrabutyl bromide as ion-pairing reagent and UV detection has been developed for aromatic sulfonated compounds. It was testified that the concentration of ion pair reagent, pH and the volume ratio of tetramethylene-oxide in mobile phase played important roles in the separation. Linearity regression equations along with linearity ranges, correlation coefficients of 0.9991-0.9996 and detection limit for determination of seven sulfonated compounds were offered. To achieve the detection of analytes in low concentration water samples, the ion-pair extraction technique was employed with ammonium tetrabutyl bromide (TBA) as ion-pair reagent and dichloromethane as extractant. Recoveries of the method were between 96.8 and 101.7%, and relative standard deviation was below 7.6%. Different concentration of 3-nitro-benzenesulfonate, dibenzal-4-sulfonate and methyl orange were detected from rainwater, tap water and electrodialysised water sample, respectively |
