Predictive modeling of pH on the transport of Co(II) Ions from aqueous solutions through supported ceramic polymer membrane.

ABSTRACT: Optimal pH is essential for efficient cobalt extraction from polymeric membrane systems, with D₂EHPA used as an extractant for Co(II) at pH < 7, achieving 47% efficiency. The pH of piperazine as a stripping agent increases to a concentration of 0.48 M, and the extraction efficiency of Co(II) > 80%. Depending on the functional group of (C₄H₁₀N₂), the optimal pH for separation was 9.8. The study revealed that pKa value was calculated to predict the ideal pH, and its value was 9.73, which is nearly to the pH, since the pH of the strip concentration and the properties of the membrane affect the extraction of cobalt at 30 ^°C. The partition ratio indicates the high distribution of the extract in supported ceramic polymer membrane (SCPM). The
