摘要：
Three n-octadecylphosphonic acid-modified magnesia-zirconia reversed stationary phases (C18PZM) are prepared via the strong Lewis base interactions between organophosphonate and magnesia-zirconia composite. And two of them are end-capped by using trimethylchlorosilane as end-capping agent in different procedures. Stability studies at extreme high pH conditions (pH 9-12) show that both the non-endcapped and endcapped columns are quite stable at pH 12 mobile phase. The reversed-phase liquid chromatographic behavior of three C18PZM stationary phas...
