详细的讨论了影响富集效率的几个因素，如离子液体的用量，水浴的温度和时间，离心时间等。使富集率达到100%，并测定了自来水及锅炉水样中的微量铁含量，回收率为83.31-104.5%，与铁-邻菲罗啉显色法分析结果一致，该方法具有操作简便、快捷、灵敏度高等特点，是一种光度法测定水中微量铁的新方法。
詳細的討論瞭影響富集效率的幾箇因素，如離子液體的用量，水浴的溫度和時間，離心時間等。使富集率達到100%，併測定瞭自來水及鍋爐水樣中的微量鐵含量，迴收率為83.31-104.5%，與鐵-鄰菲囉啉顯色法分析結果一緻，該方法具有操作簡便、快捷、靈敏度高等特點，是一種光度法測定水中微量鐵的新方法。

The factors affected the enrichment efficiency were discussed ,such as the quantity of the ion liquid ,the temperature of the water bath,time and so on. The trace iron was measured in the water of furnace when the enrichment ratio was researched to 100%.The recycling ratio was 83.3-104.5%,in accordance with the result of iron-phenanthoroline development process.This method has the character of simplicity,shortcut,high sensitivity and is a new way to measure the trace iron in the water.
