Colloidal chemistry
- Thomas Graham (1805-1869) is known as the founder of colloidal chemistry and for his fundamental research on the nature of phosphoric acid and phosphates, diffusion of gases, liquids, and solutions, adsorption of gases by metals, dialysis, osmosis, mass transfer through membranes, and the constitution of matter.

Jul 1, 2013 · Graham’s major contribution to inorganic chemistry is his paper “Researches on the Arseniates, Phosphates, and Modifications of Phosphoric Acid,” in which he elucidated the differences between the three phosphoric acids (Graham, 1833b). Before Graham’s work, the relationship between the various phosphates and phosphoric acids was very ...

Graham’s contribution to the physical chemistry of gases has been divided into six important segments (Mason, 1970). He carried out the first quantitative experiments on gaseous diffusion; no-one knew anything about this process until Graham carried out his experiments.
Thomas Graham. 1805-1869. Scottish physical chemist who studied the process of the diffusion of gases and was responsible for the development of colloid chemistry. Graham in 1831 measured the rate of diffusion of gases through a small whole and found that it was inversely proportional to the square root of its molecular weight (Graham's law).
Quick Reference. (1805–69) Scottish chemist, who became professor of chemistry at Glasgow University in 1830, moving to University College, London, in 1837. His 1829 paper on gaseous diffusion introduced Graham's law. He went on to study diffusion in liquids, leading in 1861 to the definition of colloids.
Thomas Graham. Graham's Laws of Diffusion and Effusion (Thomas Graham) A few of the physical properties of gases depend on the identity of the gas. One of these physical properties can be seen when the movement of gases is studied. In 1829 Thomas Graham used an apparatus similar to the one shown in Figure 4.15 to study the diffusion of gases ...
His most famous contributions to science include Graham’s Law of Diffusion and his pioneering work on dialysis. After having made a name for himself in Scotland, he moved south, and in 1841 founded the Chemical Society of London. As one of our precursor societies, it later merged with three other societies to become the Royal Society of Chemistry.
