The need for Ca2+ in the inactivation of bacteriophage phi X174 by lipopolysaccharide from Escherichia coli C was confirmed. Ca2+ could be replaced almost completely by Na+, but the concentration of Na+ needed was greater by more than an order of magnitude. Other bivalent ions caused inactivation in the same way as Ca2+, and the degree of inactivation varied according to the ion. At 50% inactivation of bacteriophage, the relation between the concentrations of NaCl and of bivalent or tervalent ions (Mx+) fitted the conception that NaCl was neutralizing electrostatic repulsion between virus and lipopolysaccharide by an ionic-strength effect: that is, log[Mx+] varies inversely with square root[NaCl]. The variation in effect of bi- and ter-valent ions and the low concentration needed show that this is not an ionic-strength effect but likely to involve binding to more than one site.

Amine-based absorption has been extensively used for carbon dioxide (CO2) removal processes, such as CO2 absorption from flue gas as well as from natural gas. As a reactive system in which the chemical reaction, as well as mass transfer, occur simultaneously, an experimental determination of equilibrium reaction constants, e.g. acid dissociation/protonation constant (Ka), is, therefore, necessary to be conducted. This study aims to evaluate the ionic strength effect from 0.06 to 6.0 m (mol/kg water) on the Ka value of monoethanolamine (MEA) at temperatures between 313 and 333K. The experimental results indicate that the pKa values tend to be increasing as the ionic strength increases. This is contradicting to the temperature effect where the pKa values tend to be decreasing as the temperature increases. Furthermore, the extended Debye-Hückel formulation was implemented to predict the species activity coefficients.
