以PCMS-DVB为基质的弱阳离子色谱固定相的制备及应用
Preparation and Application of Cation Exchange Column Based on Monodisperse Porouspoly(Chloromethylstyrene-co-divinylbenzene) Beads
摘要
Abstract
A kind of weakly acidic cation stationary phase was prepared by chemical modification of 6. 5 μm monodisperse macroporous poly(chloromethylstyrene-co-divinylbenzene) (PCMS-DVB)beads. The influence of the eluent type, concentration and the flow rate for the separation of four cations was investigated. Alkali metals (Li+, Na+ and K+) , ammonium (NH4+) and organic amines can be separated under the experiment conditions of using 5 mmol/L methyl vitriol as the elution with the flow rate of 1. 0 mL /min. The results showed that the four cations had good linear relationship and low detection limit. The column was further tested for the separation of inorganic cations from lycium barbarum L. The effect of resolution was consistant with the results obtained by using AAS method. In comparison with the IonPac CS12A cation exchanger column, the effect of separation of inorganic cations is almost the same as chemical modidified PCMS-DVB beads column used, whereas the analysis time is shorter than 15 min.关键词
