The invention discloses a detection kit which is used for on-site quick detection of aluminum ions in water and capable of eliminating reagent blank influences and a preparing method of the kit. In a faintly acid medium, aluminum ions in water react with chrome azurol S in the presence of a surfactant to generate a blue complex, and the shade of the blue complex is in direct proportion to the concentration of aluminum ions; a comparison with a test tube is made after the color of an aluminum ion standard color chart with reagent blank eliminated and a blank tube color are overlaid, and the concentration of aluminum ions in a water sample to be tested is obtained. The detection kit is especially suitable for on-site quick detection of aluminum ions in water. 本发明公开了种可消除试剂空白影响的水中铝离子现场快速检测试剂盒，为此，本发明还提供了该试剂盒的制备方法。本发明试剂盒在弱酸性介质中，水中铝离子与铬天青S以表面活性剂反应生成蓝色配合物，此蓝色配合物的颜色深浅与铝离子浓度成正比，将扣除试剂空白的铝离子标准色卡颜色与空白管颜色叠加后与测试管对比，得出待测水样中铝离子浓度，特别适合水中铝离子现场快速检测。
