利用电子光谱(XPS和AES)测定了水溶液中甲黄药和戊黄药在纯铜片上的吸附情况。对甲黄药吸附层的测定进一步证实了以前根据乙黄药的测定结果提出的黄药吸附机理。人们发现主要的吸附机理是,在除去含碳杂质的同时,以黄药离子取代优先吸附的氢氧基团。就戊黄药而言,它的吸附速度比 Electron spectra (XPS and AES) were used to determine the adsorption of the yellow drug and the yellow drug on pure copper in aqueous solution. The determination of the xanthate adsorbed layer further confirmed the xanthate adsorption mechanism previously proposed based on the determination of the xanthate. It has been found that the main adsorption mechanism is that xanthate ions replace the preferentially adsorbed hydroxyl groups while removing carbonaceous impurities. As for the yellow drug, its adsorption speed ratio
