The factors influencing centrifugal extraction machine extraction results
1. Water phase acidity: the influence of water PH value, and has a great influence to the extraction result, such as using acid extraction solvent extraction of metal ions, water phase equilibrium PH value has significant effects on extraction, with water phase equilibrium PH value increases, the metal extraction rate increased significantly.
2. Metal ions: the influence of the nature of metal ions is one of the important factors affecting the distribution ratio, it affect the extraction of stability and oil soluble compound, the more the charge, the smaller the radius, the formation of the extraction of compound generally more stable, so under the condition of the same extraction, over the distribution of the metal ion is often greater than the main group than the distribution of the metal ions.
3. The effects of salting-out agents: use a neutral or alkaline extraction solvent extraction, aqueous phase often add a certain amount of salting-out agent to improve the distribution of the metal than or increasing the separation factor, the effect is significant, with the increase of water phase salting-out agent concentration, separation factor is getting higher.
