Fig. 1: Adsorption mechanism and properties of PB + VC.

a Schematic illustration of the in vivo reduction-induced ion-selective adsorption (IRISA) mechanism, depicting K+ removal via PB + VC interaction and K+ transfer from blood vessels in the GI tract to normalize serum K+ levels. SZC releases Na+ when it adsorbs K+, as a comparison, PB + VC releases no ions. b K+ capacity of PB + VC, SPS, CPS and SZC in simulated fluid electrolyte solution (independent samples, n  =   3 per group). c Comparison of the ion-selectivity in a multi-element isoelectric (MEI) mixed solution containing K+, Na+, Ca2+, and Mg2+. The PB:VC mass ratios in PB + VC were systematically varied as 1:1 and 1:4 to evaluate composition-dependent effects (independent samples, n = 3 per group, Two-Way ANOVA using Tukey multiple comparisons test). All data are presented as the mean ± S.E.M. Significant differences are shown in the figures. Source data are provided as a Source Data file.
