Влияние концентрации кислоты и её соли на процессы сорбции-десорбции кислот и их солей в растворах в методе «Удерживания кислоты»

Abstract

The influence of the concentration of solutions components on acid and salt retardation is studied
by the examples of separation of binary mixes: nitric acid - nitrate of calcium, on the nitric form of anionexchanger
Levatit M-800. The sorption capacity of anionic resin toward acid is shown to be essentially
dependent on the concentration of the "concomitant"cation presenting in solution. At other equal
conditions, as it is established, the higher is the concentration of a concomitant cation, the stronger is its
positive impact on the capacity for acid.
