Quantitative analysis of silver from the thermal decomposition of chlorinated polymer contained nano silver is described. The chlorine contained in the chlorinated polymer (e.g. PVC) is liberated as hydrochloric acid gas by heating and a lot of silver produces AgCl. HNO3 and NH4OH were used for dissolving the Ag and the AgCl. The silver complex was formed by NH4OH. Then the complex was decomposed to silver by heating at 500oC and the Ag was dissolved by dilute HNO3. Recovery of silver in PVC material was 99.0%.
