چکیده

The charge of bubbles in aqucous solution is important in detemlining their interactions with particles, droplets, and other bubbles. While bubbles are known to be negatively charged in such media as water and sodium chloride solutions, they are found here to exhibit unusual positive surface charge chamcteristics in solutions of trivalent aluminum cations. Analysis of the results indicates that the reversal or bubble charge can be attributed to specific adsorption of AI +3 and its hydroxo complexes at the gas-liquid

Reversal of bubble charge in multivalent inorganic salt solutions-effect of lanthanum

It was discovered recently that the charge of gas bubbles in aqueous solution can be reduced and even reversed by the addition of multivalent inorganic saltsIn this work. the effect of LaCI3 on the charge of bubbles was investigated and found to have an effect similar to that previously observed with AICI3 and MgC12The electrokinetic behavior of gas bubbles was affected slightly by LaCI3 additi...

Adsorption of polyelectrolytes to like-charged substrates induced by multivalent counterions as exemplified by poly(styrene sulfonate) and silica.

The present study demonstrates that multivalent counterions trigger adsorption of polyelectrolytes on a like-charged substrate. In particular, adsorption of polystyrene sulfonate on silica is studied experimentally in NaCl, MgCl2, and LaCl3 solutions by optical reflectivity. While adsorption is negligible in the presence of Na(+), the polyelectrolyte adsorbs in the presence of Mg(2+) and La(3+)...

Charge reversal of colloidal particles

– A theory is presented for the effective charge of colloidal particles in suspensions containing multivalent counterions. It is shown that if colloids are sufficiently strongly charged, the number of condensed multivalent counterion can exceed the bare colloidal charge leading to charge reversal. Charge renormalization in suspensions with multivalent counterions depends on a subtle interplay b...

Interplay of pH and binding of multivalent metal ions: charge inversion and reentrant condensation in protein solutions.

Tuning of protein surface charge is a fundamental mechanism in biological systems. Protein charge is regulated in a physiological context by pH and interaction with counterions. We report on charge inversion and the related reentrant condensation in solutions of globular proteins with different multivalent metal cations. In particular, we focus on the changes in phase behavior and charge regula...

Effects of multivalent salt addition on effective charge of dilute colloidal solutions.

The effective charge Z* is often invoked to account for the accumulation of counterions near the colloid with intrinsic charge Z. Although the ion concentrations c(i) are not uniform in the solution due to the presence of the charged particle, their chemical potentials are uniform everywhere. Thus, on the basis of ion chemical potential, effective ion concentrations c(i)*, which can be experime...
