用火焰原子吸收光谱法测定微量镓的研究报道很少,其主要原因是该法灵敏度低,因此本文着重研究各种影响灵敏度的干扰因素,并试图适当提高灵敏度。我们借助于正交法进行最佳操作参数的选择和离子干扰研究,取得了满意的结果。实验表明,在总浓度不超过0.5的条件下,所试验的15种阳离子同时共存对Ga的测定 There are few reports on the determination of trace gallium by flame atomic absorption spectrometry. The main reason is the low sensitivity of this method. Therefore, this dissertation focuses on various interference factors that affect the sensitivity and tries to improve the sensitivity appropriately. We use orthogonality method for the best choice of operating parameters and ion interference studies and achieved satisfactory results. Experiments show that the total concentration of not more than 0.5 under the conditions of the 15 kinds of cations tested Simultaneous Determination of Ga
