Other Abstract系统地研究了碱性条件下(pH8~10.8)As3+;As5+;MA;DMA和AB等砷化合物在PRP-X100阴离子交换柱上的保留行为。用火焰原子吸收光谱(FAAS)测定从HPLC分离的砷化合物;即通过一根1m×0.23mmi.d.不锈钢毛细管;将HPLC柱出口与FAAS的雾化器连接起来;采用乙炔/空气火焰;在193.7nm处测定。具体研究了两个流动相(20mmol/LNH4HCO3和2.5mmol/L对-羟基苯甲酸-1.0mmol/L苯甲酸水溶液);并系统研究了pH值和缓冲液浓度对上述5个砷化合物的保留时间的影响;发现对于20mmol/LNH4HCO3体系;在pH8.7时;AB;As3+;DMA可以得到完全分离;通过梯度洗提(pH8.7到9.8;流速1.65mL/min);在15min内上述5个砷化合物可以得到良好分离;对于2.5mmol/L对-羟基苯甲酸-1.0mmol/L苯甲酸体系;在pH9.0及流速1.5mL/min时;可以在12min内将上述5个砷化合物分离。
