摘　　要：地电化学提取技术作为深穿透地球化学方法的重要组成部分,在国内外多种矿产资源勘查中取得了较好的找矿效果。在地电化学提取过程中,对埋置在土壤中的提取器持续稳定供电是进行金属离子有效提取的关键条件之一。研制了HD-2014型便携式多功能地电化学供电装置,尺寸为8.8 cm×8.8 cm×2.3 cm,重量仅为140 g,能够实现4.5 V、6 V、9 V和14 V四档恒压以及10 m A恒流输出,同时具有1~99 h的定时调节以及实时显示工作状态和信息的功能。室内和野外测试结果表明,该装置恒压及恒流输出时最大误差率分别仅为1.38%和0.60%,能够保证各测点电场强度或电流强度的一致性。Electro-geochemical extraction technique, as one part of the deep-penetrating geochemistry, has been widely used in the ex-ploration for mineral resources and proved to be very useful. During the extracting process, it is critical that provide stable and continu-ous electricity power to the extracting electrodes. By now, it is still some problem remain to be solved. A kind of device called HD-2014 portable and multi-function electro-extraction is developed. It is 8.8 cm＆#215;8.8 cm＆#215;2.3 cm large and with a weight of 140 g. Four types of constant voltage output including 4.5 V, 6 V, 9 V and 14 V can be achieved using this device. And also, stable output of 10mA can be achieved. The extraction time can be set from 1 to 99 hours and the status can be showed in time. Test results acquired indoor and in field demonstrated that the maximum error of voltage and current are 1. 38% and 0. 60% respectively, which could assure the consis-tence of the electric field and current intensity.
