Fig. 3. (A) The K⁺ concentration in solution minus background electrolyte representing K⁺ derived from K⁺–saturated SAz-1 smectite in the presence ( ${blacksquare}$ ) and absence ( ${diamondsuit}$ ) of dinitro-o-cresol (DNOC), and (B) the Ca²⁺ concentration in solution minus background electrolyte representing Ca²⁺ derived from Ca²⁺–saturated SWy-2 smectite in the presence ( ${blacksquare}$ ) and absence ( ${diamondsuit}$ ) of DNOC as a function of pH.
