A simple, rapid, and accurate extraction-spectrophotometric methods has been developed for the determination of vanadium in stainless steel and Ni-base alloys. The procedure is as follows: Take 0.5 g of sample into a beaker and add 20 ml of aqua regia, then heat and dissolve it. Furthermore add 5 ml...
