Recently, the price of tin metal has risen and the quantity of waste electrical appliances was significantly increased. In the past years, the chip units on PCB were manufactured by soldering tin-lead alloys in the solder system. However, the way to separate them was not efficient. In the published reports, distillation, ion replacement method, and symbiotic silicon fluoride acid separation were used to separate tin-lead acquisition. However, the above techniques required special equipments, and were not easy to achieve the scale-up process from the model of laboratory evaluation. Through this project, the simple and fast method to separate the lead and tin metals from solder system was conducted in three steps: dissolution process, precipitation process, and re- dissolution process. The result showed that 98.52% of lead-tin powder has been dissolved into the solution, 99.14% of tin-lead solution precipitated into tin-lead solid compound, and 78.09% of tin without any lead residues has been re-dissolved from tin-lead solid compound. With these steps, lead and tin in solder can be separated completely and efficiently, and the tin metal could also refine and reuse again. In the following years, the project will focus on the separation of tin-lead solder from waste printed circuit board (PCB) and wish to create a high value and environmental friendly procedure to solve the related issue in recycling industry." ， 欄位Project Year的內容是2015 ， 欄位Organizer的內容是"Recycling Fund Management Board" ， 欄位Executive Unit的內容是"國立台灣科技大學" ， 欄位Reporting download URL的內容是https://epq.epa.gov.tw ， 欄位Publish Date的內容是20160201 。
