【摘要】 采用紫外光谱、红外光谱研究了乙黄药在铁闪锌矿表面的吸附行为及疏水机理。结果表明 ,铁闪锌矿表面的捕收剂的吸附量随pH的升高而降低 ,表面的疏水物质主要是双黄药 ,但弱酸性时铁闪锌矿表面有少量的EPX-盐 ,弱碱性时有少量的MTC-盐更多还原

【Abstract】 Adsorption behavior and hydrophobic mechanism of ethyl xanthate on marmatite were studied by ultraviolet and infrared spectra. The results showed that the collector adsorption amount on marmatite decreased with the increase of pH value and the hydrophobic substance on the surface was mainly diethyl dixanthogen, with a little EPX - salt and MTC - salt on marmatite in case of weak acidity and weak alkaline respectively.更多还原
