Benezeth P.; Palmer D.A.; Wesolowski D.J. (2001)The solubility of pure synthetic boehmite (γ-AlOOH) has been measured over a wide range of pH (2-10, depending on temperature), and temperature (100-290°C) at 0.03 mol . kg-1 ionic strength (NaCl) in a hydrogen-electrode ...
-
Ridley M.K.; Wesolowski D.J.; Palmer D.A.; Kettler R.M. (1999)The speciation and molal formation quotients for the complexation of aluminum with sulphate were measured based on potentiometric and solubility experiments. Potentiometric titrations, utilizing a hydrogen-electrode ...

Wightman P.G.; Fein J.B.; Wesolowski D.J.; Phelps T.J.; Benezeth P.; Palmer D.A. (2001)This study reports the first potentiometric titrations of bacterial surfaces at elevated temperatures. We used a hydrogen electrode concentration cell to examine the protonation behavior of Bacillus subtilis (an aerobic, ...
-
Ridley M.K.; Machesky M.L.; Wesolowski D.J.; Palmer D.A. (2004)The adsorption behavior of metal-(hydr)oxide surfaces can be described and rationalized using a variety of surface complexation models. However, these models do not uniquely describe experimental data unless some additional ...

Benezeth P.; Palmer D.A. (2000)The molal formation quotients of cadmium-acetate complexes were measured potentiometrically (hydrogen-electrode concentration cell) from 50 to 250°C at ionic strengths of 0.1, 0.3, and 1.0 molal in aqueous sodium ...
-
Ridley M.K.; Machesky M.L.; Wesolowski D.J.; Palmer D.A. (2005)The adsorption of Nd3+ onto rutile surfaces was examined by potentiometric titration from 25 to 250°C, in 0.03 and 0.30m NaCl background electrolyte. Experimental results show that Nd3+ sorbs strongly, even at low temperature, ...
-
Wood S.A.; Wesolowski D.J.; Palmer D.A. (2000)The concentration quotients for the following reactions with acetate have been measured at temperatures from 25°C to 225°C, at saturated water vapor pressure, and in 0.1 molal NaCl medium, using a potentiometric ...
-
Benezeth P.; Palmer D.A.; Wesolowski D.J. (1999)The solubility of zincite (ZnO) has been measured in noncomplexing solutions over a wide range of pHm (4-11), and temperature (75-200°C) at 0.03 mol . kg-1 ionic strength in NaTr media (sodium trifluoromethanesulfonate, a ...
-
Wesolowski D.J.; Benezeth P.; Palmer D.A. (1998)The solubility of zincite in mildly to strongly acidic aqueous solutions, according to the reaction ZnO + 2H+ # Zn2+ + H2O, has been measured at ionic strengths of 0.03-1.0 (stoichiometric molal basis) from 50 to 290°C at ...
