Iodine adsorption method for measuring surface area of carbon blacks

摘要: Abstract Adsorption of iodine by carbon blacks from aqueous, chloroform and benzene solutions was studied conditions for estimating surface areas were standardized. It found that the adsorption black 0.3 N aqueous solution in potassium iodide (14 moles per mole iodine) after 75 hr contact as well or 15 20 days yields ultimate value which is not exceeded on raising concentration prolonging time can serve index area, irrespective nature black. to be mostly physical nature.
