Complexometric titration of thorium in solutions containing calcium, zirconium, titanium, and rare earths with the use of Fe(SCN)/sub 3/indicator was studied. A titrimetric method was developed for determining thorium in natural materials containing large amounts of zirconium and titanium with the use of iodate and oxalate precipitation, as well as a colorimetric end-paint, when small quantities of thorium are determined with arsenazo. The determination of thorium by these methods takes 8 to 12 hours. (auth)
