Adsorption kinetics of dye molecules on polymer membrane filters was written by Kost, S. H.;Breuer, H. D.. And the article was included in Berichte der Bunsen-Gesellschaft in 1992.Quality Control of 9,10-Dimethoxy-5,6-dihydro-[1,3]dioxolo[4,5-g]isoquinolino[3,2-a]isoquinolin-7-ium sulfate(2:1) This article mentions the following:
The kinetics of the adsorption of dye mols. on membrane filters made of cellulose nitrate were studied. To obtain thermodn. (activation) data the temperature was varied from 283 to 333 K. Because 1st or 2nd order kinetic laws cannot describe the exptl. results, 2 different theories are applied. In addition to a classical concept a new equation based on fractal theory is tested and proved to be suitable for adsorption data is tested. The fractal parameters, fractal dimension Ds, and fraction dimension Df, are in excellent agreement with other fractal kinetics experiments In the experiment, the researchers used many compounds, for example, 9,10-Dimethoxy-5,6-dihydro-[1,3]dioxolo[4,5-g]isoquinolino[3,2-a]isoquinolin-7-ium sulfate(2:1) (cas: 316-41-6Quality Control of 9,10-Dimethoxy-5,6-dihydro-[1,3]dioxolo[4,5-g]isoquinolino[3,2-a]isoquinolin-7-ium sulfate(2:1)).
9,10-Dimethoxy-5,6-dihydro-[1,3]dioxolo[4,5-g]isoquinolino[3,2-a]isoquinolin-7-ium sulfate(2:1) (cas: 316-41-6) belongs to isoquinoline derivatives. Quinoline is a mancude organic heterobicyclic parent, an azaarene, an ortho-fused heteroarene and a member of isoquinolines. It protonates to form salts upon treatment with strong acids, such as HCl. It forms adducts with Lewis acids, such as BF3.Quality Control of 9,10-Dimethoxy-5,6-dihydro-[1,3]dioxolo[4,5-g]isoquinolino[3,2-a]isoquinolin-7-ium sulfate(2:1)
