A method has been proposed for the determination of micro Fe, Cr, Mn, Ca, Mg, Al, Sr, Ba in the KDP Crystals and its culture solutions by ICP AES. The effect of matrix concentration on line intensity of determined elements has been investigated.

• 用ICP－AES法测定KDP晶体及其培养液中微量的Fe、Cr、Mn、Ca、Mg、Al、Sr、Ba，并对KDP基体对被测元素谱线强度的影响进行考察。
