通过吸附研究、电泳迁移率测量、缸外光谱和哈里蒙德浮选管试验,对辛基异羟肟酸在电解二氧化锰上的吸附进行了研究。室温下的吸附测量和浮选研究表明,吸附密度和浮选曲线的峰值出现在 pH 9左右。红外光谱显示,二氧化锰表面出现碱性的异羟肟酸锰化合物。电泳迁移率研究指出,异羟肟酸特性吸附在二氧化锰/水界面上。在升温条件上的吸附测量表明,吸附密度随温度升高而增加。从而认为,吸附的活性成分是异羟肟酸。
Adsorption of octylhydroxamic acid onto electrolytic manganese dioxide was studied by adsorption studies, electrophoretic mobility measurements, out-of-column spectroscopy, and Halimonde flotation tube tests. Adsorption measurements and flotation studies at room temperature show that the peak of adsorption density and flotation curve appears at pH 9 or so. Infrared spectroscopy shows that manganese hydroxamate compound appears on the surface of manganese dioxide. Electrophoretic migration studies indicate that hydroxamic acid properties are adsorbed on the manganese dioxide / water interface. The adsorption measurements at elevated temperature show that the adsorption density increases with increasing temperature. Therefore, it is considered that the active ingredient adsorbed is hydroxamic acid.
