抄録

Studies were made on the determination of microamounts of Co and Fe in metallic nickel. After extracting the thiocyanate complexes of Co and Fe in the presence of Ni, simultaneous determination of Co and Fe were made photometrically and satisfactory results were obtained. However, the above mentioned simple method was not suitable for the determination of trace amounts of Co and an improved method was devised to determine about 0.001% of Co contained in metallic nickel.
