title: A new catalytic method for determination of copper in blood serum.
abstract: A sensitive, accurate and fast catalytic method is proposed for determination of copper in blood serum, based on a new catalytic reaction-oxidation of 1,3,5-trihydroxybenzene by H(2)O(2). The method permits copper to be determined down to 1 ng/ml in a sample of 0.10 ml of blood serum with a sufficient accuracy and precision even in sera with abnormally low copper assay. Twenty samples can be analysed per hour by a very simple procedure without separation of the metal to be determined.
