本文据X射线光电子能谱分析(XPS)技术的原理及有关金的大量实验资料论证了王玉明等同志在“含金硫化物矿物中不可能存在负价金”一文中提出的“粒径小至500nm的自然金微粒可能具83e/V的Au4f_(7/2)结合能”以及提出“电子结合能与金属粒径具正相关关系”的论点是不成立的。并进一步阐明笔者所报道过的微细浸染型金矿含金硫化物中测出之Au4f~(7/2)=82.5-82.9eV的电子结合能既不能由表面化学位移所引起,也不是由于金作为纳米级簇团呈孤岛状分布在碳、Al_2O_3和SiO_2表面形成金属原子簇芯层位移所引起。迄今对这种与金属金有1.1eV以上结合能负位移的最好解释仍是硫化物矿物中存在着负价金。此外根据~(197)Au穆斯鲍尔谱分析数据说明具+3.65±0.05mm/s同质异能位移的“化学结合金”不能肯定为阳离子金,也不是金的碲化物。
In this paper, X-ray photoelectron spectroscopy (XPS) technology and a large number of experimental data on gold demonstrated that Wang Yuming and other comrades in the “gold-bearing sulphide minerals can not exist in a negative price,” a paper presented in the “ The argument that 500 nm natural gold particles may have a Au 4f 7/2 bonding energy of 83e / V and that ”there is a positive correlation between electron binding energy and metal particle size“ is not valid. And further clarified that the electron binding energy of Au4f ~ (7/2) = 82.5-82.9eV measured in the gold-bearing sulfides of finely disseminated gold mine reported by the author is neither caused by surface chemical shift nor due to the fact that gold As nanoscale clusters are island-like distribution in the carbon, Al 2 O 3 and SiO 2 formed on the surface of the metal core cluster displacement caused. To date, the best explanation for this negative shift of more than 1.1 eV with metal gold is still the negative in sulfide minerals. In addition, according to ~ (197) Au Mauserbaum spectral analysis data, ”chemically bound gold" with a displacement of +3.65 ± 0.05 mm / s isomorphism can not be positively identified as cationic gold nor telluride of gold.
