Two different buffer systems for the separation of 12 aromatic hydrophobic sulfonates by micellar electrokinetic chromatography (MEKC) were developed. The following buffer systems were used: aqueous phosphate buffers containing either cetyltrimethylammonium bromide (CTAB) or sodium dodecyl sulfate (SDS). Eleven aromatic sulfonates were simultaneously separated in less than 35 min employing 20 mM phosphate buffer, pH 7.0 containing 50 mM SDS and 10% of acetonitrile.
开发了两种不同的缓冲体系，用于通过胶束电动色谱法（MEKC）分离12种芳香族疏水磺酸盐。使用了以下缓冲体系：含有十六烷基三甲基溴化铵（CTAB）或十二烷基硫酸钠（SDS）的水性磷酸盐缓冲液。使用含有50 mM SDS和10%乙腈的20 mM磷酸盐缓冲液（pH 7.0），在不到35分钟的时间内同时分离出11种芳香族磺酸盐。
