Studies of removing copper ions from water with the seed coats of grain crops

This paper presents the studies of sorbing copper ions in simulated water with seed coats barley, wheat, and oat grains. Isotherms were built for Cu 2+ sorption at initial concentrations 0.315-62.947 mmol/dm 3 . It is shown that isotherms all grain samples correspond IUPAC 1b are described by Langmuir equation confidence degree 0.999. also runs intensively contaminant concentration ranging from 0.315 through 15.737 , while rate observed decreases significantly exceeding which works out to 1,000 mg/dm The indicative monomolecular adsorption running.
