Impact of Temperature, pH, Electrolytes, Approach Speed, and Contact Area on the Coalescence Time of Bubbles in Aqueous Solutions with Methyl Isobutyl Carbinol.

At low MIBC concentrations, particularly in the range of 0 to 100 ppm presented in Figure 7 c, a clear trend is observed in which divalent salts (CaCl 2 , MgCl 2 ) provide longer coalescence times than monovalent salts (NaCl, KCl, KI), and all salts exhibit a stabilizing effect compared to pure water.
