Hi James! All I have is Arthur Thomas' short account of Freundlich's method, and a bibliography of Freundlich's other articles on collosol precipitation by electrolytes.
Here are the citations. Freundlich: Z. Physik. Chem., 44,129 (1903). Freundlich und Schucht: Z. Physik. Chem., 85, 641 (1913) Freundlich und Scholz: Kolloidchem. Beihefte, 16, 267 (1922) Freundlich: Z. Physik. Chem.,73, 385 (1910) Freundlich und Lindau: Kolloid-Z., 44, 198 (1928) Freundlich und Slottman: Z. Physik. Chem., 129, 305 (1927) Arthur W. Thomas has an entire chapter of about twenty-five pages devoted to the precipitation of sols by electrolytes. But he is fairly sketchy about the calculations. If you think it will be of any use, send me your address and I will send you a copy. My first glance at this material makes me think a lot of experimentation and thoughtful analysis will be needed to reconstruct the method in detail. Best regards, Matthew
