ICP-AES法测定钢铁中微量钙

ICP-AES Determination of Calcium in Iron and Steel with the Method of ICP-AES

用ICP—AES法测定钢铁中的钙不需经化学分离、富集，大大降低了空白值，方法简便、快速、灵敏度高，样品用酸溶解后直接测定，测定下限可达0．0005％。

ICP - AES determination of calcium in iron and steel is simple, quick, sensitive and direct. It does not require separation and collection by＇using chemical methods. So the blank is much less than that of other chemical methods. Sample is directly measured after dissolving with acid. The determination limit is low to 0. 0005%.
