查询词典 acid casein

We present a simple approach to determine the content of casein in crosslinked polyacylamide, i. e., protein molecules are complexed with copper ions by biuret reaction. The polymer containing proteins is cinerated at high temperature and then the residue is dissolved into nitric acid. Protein content is measured by determining concentration of copper ion in nitric acid solution using atomic absorption spectrum.
