活性炭从硫脲液吸附黄金介绍了巴西里约热内卢大学材料冶金工程系用活性炭从硫脲溶液中回收黄金的研究。发现,在15~55℃下用活性炭吸附金离子及硫脲的机理与弗劳特里奇(Freundlich)吸附等温线能很好相符。对金的吸附是一种放热反应,而对硫脲的吸附是一...
Activated Carbon Adsorption of Gold from Thiourea Liquid The paper introduces the research of gold recovery from thiourea solution by activated carbon in the Department of Materials and Metallurgy, University of Rio de Janeiro, Brazil. It was found that the mechanism of adsorption of gold ions and thiourea on activated carbon at 15-55 ℃ was in good agreement with the Freundlich adsorption isotherm. The adsorption of gold is an exothermic reaction, while the adsorption of thiourea is a ...
