OSTI ID:4149834
A method is described for the photometric determination of thorium in monazites with the arsenazo II reagent directly after the decomposition of monazite without separating thorium from the impurities. No interference is caused by phosphates (up to 30% P/sub 2/O/sub 5/), Zr, Ti, Mo, V, W (up to 0.2 to 0.5%), rare earths, and other elements. The time for a determination is 25 to 30 min. The relative error is not more than 3 to 5%. (auth)
