| 摘 要： | 以不同极性的GDX树脂和柱型富集装置,研究了其对水中微量石油的富集性能及洗脱、贮存条件。结果表明,水样流速在30mL/min以下时,富集效率均在90%以上且动态吸附容量较静态吸附容量高;在9种洗脱试剂中,乙醚最佳;水样富集后以氮气充满富集柱干态保存为最好;将DGX-502用于实际样品中微量石油的富集与测定,结果较好。

| Abstract: | Two micromolecular porous resins, GDX-102 and GDX-502, were used to concentrate the trace petroleum in water. The conditions of concentration, elution and reservation have been studied. It has been shown that both GDX resins are of high concentration efficiency and large adsorptive capacity. Ethylether was the best eluting agent among 9 agents with the elution efficiency of 101.2% for GDX-102 and 99.4% for GDX-502. The experimental results showed that the best reservation method was in dry state of nitrogen. After seven days the loss of petroleum on GDX-502 was less than 4.6%. |
