Huizhou integrated circuit board scrap gold and silver content detection and analysis

Scrap gold and silver content detection circuit boards across the country to undertake the analysis of the circuit board circuit board metal content detection and analysis, not only contains a lot of copper, palladium and other precious metals also contains gold and silver, copper smelting and processing raw brick, China as scrap circuit boards The main import processing countries, has a huge production capacity, and different board, where a huge difference in the content of various metals, Foshan fine testing center is also a master of science in practical analytical methods to detect long-term practice, to provide you with credible The results of the analysis. Content by atomic absorption method for detecting metal in the circuit board, the results show that the circuit board testing laboratories, accounting for 37.30% of the total weight of the metal mass, the higher Cu, Sn, Fe, Pb, Zn content. Metal dissolution experiments showed strong acidic solution of pH = 1, the effect of metal dissolution significant; while in simulated acid rain pH = 4 solution that only a small amount of Zn and Cu dissolution at pH = 7 in neutral solution metal dissolution were below the detection limit (0.4 mg / kg).
