| Abstract: | The silanized silica was firstly encapsulated with chloromethylstyrene and then quaternized by N, N-dimethylbenzylamine. Thus a new kind of strong anion stationary phase was prepared. This strong anion silica column has superior separation ability for the anions by using indirect ultraviolet detection with wavelength at 254 nm and the mobile phase of V(methanol):V(0.125 mol/L NaH2PO4) = 60:40. Moreover, separation of mono- and di-petroleum sulfonates in Yumen sample could also be good with gradient elution. The sample was first eluted with 100% A V(methanol):V(water) = 60:40] for 1 min, then the eluent was changed linearly to 100% B V(0.125 mol/L sodium phosphate monobasic):V(methanol) = 60:40] within 1 min, then the sample was continuously eluted with 100% B for 6 min. |
