Molybdenum blue

This colorimetric method is ineffective when comparable amounts of arsenate are present in solution with phosphate. This is due to the strong chemical likeness of arsenate and phosphate. The resultant molybdenum blue for arsenate, using the same procedure, does produce a slightly different spectral signature, however.

Aug 26, 2015· These authors also showed evidence that the species responsible for this synergistic behaviour was a molybdenum blue species containing a 11 ratio of As(V)P. Dhar et al. have since provided further evidence for a combined As(V)/P product in their As(V) method; in the presence of sufficient P, the reduction process was complete in 10 min, but

Welding Method of Stainless Steel and Molybdenum

Welding Method of Stainless Steel and Molybdenum

Jul 09, 2019· Welding Method of Stainless Steel and Molybdenum. Since the physical properties of molybdenum and molybdenum alloys differ greatly from those of stainless steel, many problems arise during the welding process. In their soldering, when heated to 400 ° C, slight oxidation occurs; when it is above 600 ° C, it is rapidly oxidized to MoO3 compound.
