摘 要：<正> In this study,fluorinating vaporization combined with ETV-ICP-AES technique was used to determineyttrium for which refractory carbide is easily formed.The absolute detection limit is 12 pg,and three-ordermagnitude of improvement is obtained in comparison with the conventional vaporization ETV-ICP-AES.Nomemory effect is observed.The relative standard deviation is better than 5%.Some factors affecting fluorinatingvaporization,including matrix effect are discussed.This technique is applied to determine yttrium in La2O3.
