摘要
随着金价高涨,黄金成为舆论的焦点.市面上金覆盖层产品推陈出新,市占率增加,其检测需求也逐年增大.本实验对金覆盖层产品样品前处理方法进行改进,极大的简化了前处理流程,利用电感耦合等离子体原子发射光谱法(ICP-AES法)测定金质量与金层厚度,实验结果表明本实验方法测量结果与国家标准结果相一致.本实验方法不仅操作便捷,且结果准确可靠.
Abstract
Gold has increasingly captured the public's attention due to its soaring prices.The recent introduction of innovative gold-plated products has significantly boosted their market share,and the demand for testing these products has been on the rise annually.In this study,we have refined the sample pre-treatment process,making it notably more efficient and straightforward.Employing Inductively Coupled Plasma Atomic Emission Spectrometry(ICP-AES)for measuring the mass and thickness of the gold layer,we have demonstrated that our experimental approach aligns with national standards.This method has proven to be convenient,accurate,and reliable for such analyses.
