ICP-AES法测定黑色石材全组分元素的研究

Study on All-components of Black Stones by Inductively Coupled Plasma-Atomic Emission Spectrometry

采用偏硼酸锂熔样,电感耦合等离子体原子发射光谱(ICP-AES)法对黑色石材实现了一次熔样、全组分同时分析。对影响其光谱测量的各种因素进行了较为详细的研究,确定了实验的最佳测定条件。结果表明,方法的检出限为0.005～0.796μg·mL-1,回收率为93.16%～107.80%,RSD小于3.79%。该法准确、快速、简便,应用于黑色石材中全组分的测定,结果满意。

The lithium metaborate fusion sample and the Inductively Coupled Plasma-Atomic Emission Spectrometry (ICP-AES) method are used in the analysis of all-components of black stones.The various factors affecting spectrum intensity were examined in details.The optimum conditions for the test is decided. The limit of the method is 0.005～0.796μg·mL-1.The recycling rate ranks from 93.16% to 107.80%.RSD is less than 3.79%.This method is accurate,quick-acquired and convenient.The examination of all-components of black stones is satisfactory.
