摘　　要：微流控化学芯片目前正成为环境监测的研究热点，而将电化学检测器集成在微流控芯片上是实现芯片实验室最有效途径之一。利用自制集成电导检测微流控化学芯片测定了土壤中铁总含量，讨论了影响土壤中铁总含量测定的多个因素，同时用原子吸收光谱法验证了测定结果的准确性。该结果为实现微型全分析系统整体集成和样品现场分析奠定了一定的理论与实验基础。Microfluidic chemic chips is becoming a hot point in the research field of environment determination. It is one of the available approaches to realize the true concept ： Lab-on-a-chip with integration of electro-detector on microchip. The iron in soil was detected by means of microfluidic chemic chips with integrated conductivity in this work.. Many factors that affected detection of iron ion were analyzed. The veracity of the determination of iron in soil was validated with Atomic Absorption Spectroscopy, The research is helpful for the truly integration of miniaturized total analytical system （μ-TAS ） and μ-TAS application for in-situ and in-fields in t, coming future.
