酸碱软硬度的势标度在浮选剂结构性能研究中应用

在浮选药剂结构性能研究中，软硬酸碱理论存在难以定量计算的问题，为解决该问题，在浮选药剂的研究领域引入了酸碱软硬度的势标度，并扩大了软硬酸碱理论的应用范围.提出了一个浮选药剂选择性判据，该判据是酸碱软硬度的势标度和药剂分子前线轨道能级的函数，以赤铁矿阴离子反浮选捕收剂RA-315和硫化矿浮选捕收剂为例，应用药剂选择性判据研究了药剂结构性能，所得结论与浮选试验结果相符，从而证明了酸碱软硬度的势标度对药剂结构性能定量研究具有较大的促进作用.

Application of Acid-Base Potential Scale in Structure Performance Study of Flotation Reagents

Acid base potential scale was introduced to overcome the difficulties caused by acid basic theory in the quantitative research on structure performance of flotation reagents， and to expand the scale of application of acid basic theory. The selective criterion was presented， which is the function of acid base potential scale and frontier molecular orbital energy level of flotation reagents. With this selective criterion， the structure performance of RA 315 as anion reverse flotation collector of hematite and sulphide mineral collector was studied. The conclusions are in accordance with the flotation test results， which indicates that acid base potential scale plays a great promotion role in the quantitative research on structure activity of flotation reagents.
