Colorimetric Determination Of Copper Ions Based On The

Aug 31, 2013018332We have developed a method for the colorimetric determination of copper ions Cu2 that is based on the use of silver-coated gold nanorods AuAg NRs. Its outstanding selectivity and sensitivity result from the catalytic leaching process that occurs between Cu2, thiosulfate S2O3 2, and the surface of the AuAg NRs. The intrinsic color of the AuAg NRs changes from bright red to

How Silver Is Made Material Making History Used

Silver is rarely found alone, but mostly in ores which also contain lead, copper, gold, and other metals which may be commercially valuable. Silver emerges as a byproduct of processing these metals. To recover silver from zinc-bearing ores, the Parkes process is used. In this method, the ore is heated until it becomes molten.
