WebSeparations of copper from nickel, and of copper from cobalt are described, using cation exchange resins. The apparatus, resin, and separatory technique are outlined. 2.5M sodium chloride is used for liberation of nickel and cobalt from the resin. Nickel and cobalt are determined titration with ethylenediamine tetraacetic acid solution, using ... WebFrom a quick google search it seems like there are some who argue that you purify less contaminating protein with cobalt, but it also binds less protein in general. I would say to use nickel unless you have a particular reason not to. In contrast, the selectivity for 6xHis sequence binding is: So in principle Ni2+ offers the best of both worlds ... 26 january 2022 photo editing WebThe cobalt 2+ has been reduced to solid Co metal so will not be eluted by EDTA.
