摘要: 研究了α-亚硝基β-萘酚对赤铁矿的捕收性能及吸附规律,导出了吸附方程和吸附速率方程用药剂基团电负性理论计算以及红外吸收光谱法论述了其作用机理α-亚硝基β—萘酚主要是以N O键合原子与赤铁矿表面的Fe(Ⅲ)形成N O五元环螯合物而化学吸附.同时也兼有多层的,不均匀的物理吸附
关键词 α-亚硝基β-萘酚赤铁矿电负性螯合特性    
Abstract:Based on theoretical calculation of electronegativity of groups offlotation-reagent and method of infra-red adsorption spectroscopy, the collection andadsorption of α-nitroso-β-naphthol in hematite flotation have been studied. The chemicaladsorption seems to be predominant owing to formation of pentacyclic nitrosyl chelate com-pound by atoms of nitrosyl bond in α-nitroso-β-naphthol together with Fe~(3+) on hematitesurface. Meanwhile, the non-uniform multi-layer physical adsorption is also occurred.
Key wordsα-nitroso-β-naphthol    hematite    electronegativity    chelate property
