泡塑富集——原子吸收光谱法测定矿石样品中的金元素

Determination of gold in ore samples by atomic absorption spectrometry after foam plastic Preconcentration

在经济社会高速的发展背景下对于矿产资源的需求也越来越大,由此造成矿产资源开采逐渐匮乏,出资按开采边界逐渐降低的情况,这就需要不断提升生产工艺技术水平,同时也是金的检测工作面临的难度越来越大。而在开采金矿的过程中金检测的精准度是影响金矿开采的重要因素。火焰原子吸收光谱法在矿山地质样品分析中应用最为广泛,该方法不仅检测速度快,而且非常容易操作,使用过程中不需要过多的成本投入,测定经过非常精准,居于较高的重现性,尤其是适用于批量的分析地质样品。

Under the background of high-speed economic and social development,the demand for mineral resources is also increasing,which results in the gradual shortage of mineral resources exploitation and the gradual decrease of investment according to the mining boundary.This requires the continuous upgrading of production technology level,but also the increasing difficulty of gold detection face.In the process of mining gold,the accuracy of gold detection is an important factor affecting gold mining.Flame atomic absorption spectrometry(FAAS)is the most widely used method in the analysis of geological samples in mines.This method is not only fast in detection,but also very easy to operate.It does not need too much cost investment in the process of use.The determination is very accurate and has high reproducibility,especially suitable for the analysis of geological samples in batches.
