The process for forming the coating broadly comprises degreasing the magnesium or magnesium alloy product in a degreasing solution, cleaning the product in a highly alkaline cleaning solution, deoxidizing the product in a deoxidizing solution, and immersing the product in the coating solution for a time period of 15 minutes to 90 minutes.

Abstract: Disclosed is a method of preparing a rhenium complex by use of a borohydride exchange resin, including dissolving perrhenic acid in a solution containing ethylenediamine tetraacetate, mannitol and stannous chloride to obtain a perrhenic acid solution (step 1), which is then mixed with disulfide in the presence of a borohydride exchange resin and reacts at room temperature, to obtain a rhenium complex (step 2). The preparation method of the current invention is characterized in that rhenium is reduced to have a desired oxidation number through the dissolving of the step 1, whereby the reaction of the step 2 can occur at room temperature. In addition, use of the borohydride exchange resin as a reducing agent results in direct formation of the rhenium complex of sulfide from disulfide, without the need of synthesis of thiol-protected S-precursor. Therefore, radioactive pharmaceuticals having high values can be economically and efficiently produced.
