| Abstract: | This paper studies an analytical method to determine thorium content in rare earth concentrates by ICP-AES. The optimum operation parameters of instrument are tested by selecting the analytical lines. The recoveries of standard addition can reach 98%～101% with RSD less than 3%. Being convenient, rapid and accurate, the determination method is fit for thorium range between 0.30%～8.00%. |
