| Abstract |
Recently, the technology development that can prevent environmental pollution and reduce resource consumption is becoming more important. Therefore, the minimization of the waste incineration and landfill, and maximization of the waste recycling can prevent environmental pollution and save resources and energy. Currently, approximately 150 tons of ammonium nitrate have been generated every month in Gumi Industrial Complex and Gyeongbuk Industrial Complex, and they are treated in advanced treatment system mainly by paying expensive wastewater. Therefore, there is growing interest in technologies that can reduce wastewater costs and added value by utilizing ammonium nitrate wastewater. In this study, the method of removing the unnecessary heavy metals and contaminants was optimized to utilize the ammonium nitrite produced in the oxide metal manufacturing process. The removal efficiency of Zn and Fe by solvent extraction method using D2EHPA extractant was about 95.1% and 96.6%. Also, Using Cyanex 272 extract, 96.1% of Ni and 93.5% of Co were removed. Consequently, this study shows that D2EHPA and Cyanex 272 may be suitable extractant for heavy metal from the synthesis solution. Extraction efficiency and separation factor could be increased by controlling pH and extractant concentration.
