Sorption cleaning of solutions from naphthenic acid
In the paper the problem of cleaning of spent or intermediate solutions of chemical, metallurgical, mining and mining-refining enterprises from naphtenic acids by sorption method has been considered. For the first time a more effective sorbent - special tissue PM - has been tested. During experimental researches it has been established that the special tissue PM has the greater efficiency at deleting petroleum acids from solutions. Besides the application of this sorbent has a number of essential advantages: does not demand special acidification of cleaned solution; has greater sorbate capacitance.
