查询词典 cations

The highest occupied molecular orbit and the lowest unoccupied molecular orbit are calculated, and the energy gap of the two orbits determines the activity of the reagents, and yet, in an alkaline solutions for flotation, the HOMOs of the corresponding ions decide the rigidity of the reagents and therefore determine the reaction activity with different rigidity metal cations in minerals, which vary flotation performance to different minerals, and the experimental results were verified.
