Abstract Chemical and galvanic corrosion experiments at 35 C show that ductile vanadium is resistant to corrosion in substitute ocean water. It is also resistant in 60 percent sulfuric and 20 percent hydrochloric acids but corrodes rapidly in nitric acid solutions. Vanadium is less noble than stainless steel and copper and more noble than aluminum, magnesium and steel (SAE 4130) in substitute ocean water. 6.3.18

Abstract A collaborative study was conducted to compare a spectrophotometric molybdovanadate method and the official gravimetric quinoline molybdate fertilizer method 2.025(b), slightly modified, with the official volumetric method 20.032. Six collaborating laboratories analyzed dilute acid solutions of the ash of 5 different kinds of fruit products and an aqueous solution containing only KH2PO4 by each of the 3 methods. Satisfactory agreement between laboratories and good agreement between methods were obtained. From the results of this collaborative study it appears that the quinoline molybdate and the molybdovanadate methods are more accurate and precise than the official volumetric method. It is recommended that both the spectrophotometric molybdovanadate method and the gravimetric quinoline molybdate method for the determination of phosphorus in fruits and fruit products be adopted as official first action.
