通过用红外光谱、扫描电镜和透射电镜等现代分析技术对聚酰胺吸附金的机理进行了综合性的研究．实验结果表明，在稀酸介质中，聚酰胺对金的吸附属于一种基于范德华力和氢键的物理吸附．
Through the use of modern analytical techniques such as infrared spectroscopy, scanning electron microscopy and transmission electron microscopy, the mechanism of polyamide adsorption of gold has been comprehensively studied. The experimental results show that in dilute acid medium, the adsorption of gold by polyamide belongs to a physical adsorption based on Van der Waals forces and hydrogen bonding.
