The Continuous Titrimetric Analysis and Determination of Copper, Lead and Tin in Waste PCB

摘要：

The contents of copper, lead and tin in waste printed circuit boards were titrimetric analysis and determinated by EDTA continuous titration. The waste PCB where electronic parts and components have been removed were used. It was decomposed by the solvent of hydrochloric acid and hydrogen peroxide. The analysis results of standard sample recovered experiment showed that the recoveries were 98.40~102.0% meeting the requirements for waste. The method was proved accurately, reproducibly, simply and quickly. It will have guiding significance for recycling waste printed circuit board.
