合成了含有单羧基和双羟肟基的新型螫合捕收剂HAD。研究了其对一水硬铝石和铝硅酸盐矿物的浮选行为及浮选机理。结果表明，该捕收剂在中性条件下能有效分离一水硬铝石与铝硅酸盐矿物。作用机理可能是HAD中-COOH和-CONHOH的O原子之间协作与一水硬铝石表面Al点形成螯合物而发生化学吸附，在铝硅酸盐矿物表面主要发生的是物理吸附。

Collector HAD was synthesized, containing both mono - carboxyl group groups. The flotation behaviors of diaspore and aluminosilicate minerals were investigated flotation results revealed that a good separation could be realized by using HAD as co searches in interaction mechanism indicated that the interaction of the collector on the and double - hydroxycarbamoyl by using HAD as collector. The llector in neutral medium. The re- diaspore surface was mainly chemi- cal adsorption, the chemical adsorption of HAD on diaspore may take place through - COOH, - CONHOH and Al sites forming chelate rings, and the adsorption on kaolinite and illite was mainly dominated by physical adsorption.
