基于电磁感应加热效应作为样品前处理的方式，探索一种用于环境样品现场快速分析的前处理方法，针对现场处理样品少量的特点，采用功耗小的装置解决设备小型化，进而解决电源供电方式难题，通过电磁感应加热快速升高温度，使环境样品中的重金属以离子形式释放到溶液中，本研究通过优化实验条件，确定最佳电磁感应加热的前处理条件，然后应用便携式微分电位溶出仪进行快速测定。在最佳条件下，测量不同环境样品中Pb的加标回收率为78%～81%,Cd的加标回收率为70%～77%,相对标准偏差的范围为1.33%～9.95%,基本满足检测要求。基于电磁感应加热的前处理设备实现微型化和便携化，这使得在现场快速检测成为可能。
Abstract：Based on the electromagnetic induction heating effect as the method of sample pretreatment, a pretreatment method for the on-site rapid analysis of environmental samples was explored, according to the characteristics of a small number of samples processed in the field, a device with low power consumption was used to solve the miniaturization of the equipment, and then the problem of power supply mode was solved, and the temperature was rapidly increased through electromagnetic induction heating, so that the heavy metals in the environmental samples were released into the solution in the form of ions. A portable differential potentiometer is then used for rapid determination. Under the optimal conditions, the spiked recoveries of Pb in different environmental samples were between 78%-81%, the spiked recoveries of Cd were between 70%-77%, and the relative standard deviation ranged from 1.33%-9.95%, which basically met the detection requirements. Miniaturization and portability of pretreatment equipment based on electromagnetic induction heating make it possible to quickly inspect in the field.
