제안 방법
- At the end of each test, metal concentrations in anolyte, cath이yte, outflow, and filter paper were also analyzed. Soil pHs were recorded for each section before drying them in an oven fbr chemical analysis and water content evaluation.
- At the constant current mode, the output current was regulated to the selected value, while output voltage was varied with the load requirements. Constant current mode was selected in this experiments to sustain a constant rate of production of electrolysis products at the electrodes and simplify analysis of the chemistry at the boundaries.'이 Copper wires were used as voltage probes to measure the electric potential distribution of the soil specimen in a horizontal direction.
- In order to estimate the effects of operation conditions of electrokinetic processes in the removal of heavy metals from the mine tailings, electrokinetic reactors just saturated with water in which any other electrolyte was not contained, were run under constant current and constant potential conditions. In the operation of the process, changes in pH, electric current, electric potential, osmotic flow, and contaminant distribution were investigated.
- According to the these differences, chaises of procedure conditions were expected in electrokinetic remediation at the real site. Therefore, the studies were carried out to estimate the applicability of electrokinetic technique in the metal mining deposit, same real contaminated soils which have been aged for longer periods of time. For those experiments, a mine deposit soil containing high concentration of heavy metals especially, Cu, Cd, Pb, and Zn were selected.
대상 데이터
- The soil specimen fbr the electrokinetic experiments were prepared with metal mine tailings, which were collected from the "I" mine located at the North Eastern suburban area in Busan Metropolitan City. The main mining metals were gold, silver, copper, and tungsten.
- Therefore, the studies were carried out to estimate the applicability of electrokinetic technique in the metal mining deposit, same real contaminated soils which have been aged for longer periods of time. For those experiments, a mine deposit soil containing high concentration of heavy metals especially, Cu, Cd, Pb, and Zn were selected.
- The reactor was made of acrylic material with 5 mm thickness for electrical insulation and also to resist the lateral compaction pressure. The dimension of the reactor was 10 cm in width, 15 cm in hight, and 29 cm in length. The selected electrode spacing was about 16 cm.
- The equipment fbr this study was composed of a electrokinetic remediation set, graduated cylinders, electric circuit, power supply, pH meter, and multitester. Fig.
