Stabilization of lyophobic colloids by hydrolyzed metal ions
Abstract
The coagulation and reversal of charge of silver bromide and silver iodide sols (aged and in statu nascendi) by chromium (III) nitrate and hafnium tetrachloride has been investigated as a function of pH. Turbidity, mobility and adsorption measurements were performed and the results interpreted in terms of the hydrolysis of chromium(III) and hafnium ions.
