黑色石材全组分元素同时测定的研究

Study on the Simultaneous Determination of 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。

It is reported in this paper that the lithium inelaborate fusion method decompose technique is used in the Inductively Coupled Plasma - Atomic Emission Spectrometry (ICP-AES) method determination of all - components of black stones. The various factors affecting spectrum intensity were examined in details. The optimum conditions for the determination is tested and discussed. 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.It is used in the determination of all - components of black stones with the result is satisfactory.
