Improved separation of iron from copper and other elements
Sep 01, 1980 IronIII can be separated from copperII and many other elements by eluting these from a column of AG1-X4 anion-exchange resin with 8M hydrochloric acid, while ironIII is retained and can be eluted with 0.1M hydrochloric acid. The separation is much better than the customary one with 3.5M hydrochloric acid. Columns containing only 8.8 ml 3 g of resin can separate traces or up to more ...
Copper Scrap an overview ScienceDirect Topics
No. 1 copper scrap has a minimum of 99 copper and is often just remelted. No. 2 copper consists of unalloyed scrap, with a copper content of at least 94 with a nominal content of 96 Cu. Light copper scrap contains between 88 and 92 copper. These types of copper scrap usually have to be refined to obtain the quality required.
Electroless Copper Plating A Review Part I
The overall electroless copper plating reaction is theoreti-cally given as Cu2 2HCHO 4 OH- Cu H 2 2H 2 O 2 HCO 2-This equation calls for consumption of four hydroxyl ions and two molecules of formaldehyde for each atom of copper deposited. Certain side reactions may also take place, how-

Selective separation of copper II and cobalt II from
Mar 21, 2011 Performance of continuous crossflow micellarenhanced ultrafiltration MEUF method was investigated for the selective separation of copper Cu 2 and cobalt Co 2 from the aqueous phase using sodium dodecyl sulfate SDS as an anionic surfactant and iminodiacetic acid IDA as a chelating agent.Operating parameters such as operating time 10120 min, crossflow rate
Liquidliquid extraction and separation of copperII and
endothermic. The extraction of copper was lowest when chloroform was used as the diluent. Separation and recovery of copper from a synthetic copper-nickel solution containing 6.35 gL CuII and 0.58 gL NiII was carried out using 20vv LIX 984N. The separation factor DCuDNi was found to be pH-dependent. A two-stage batch ...
