Determination of Phosphorus in Human Hair by Spectrophotometry of Phosphomolybdenum Blue / 昆明医科大学学报

ABSTRACT

This paper reported a method of determination of phosphorus in human hair by Spectrophotometry of phosphomolybdenum Blue.Samples were decomposed by means of dry ashing.Vitamin C was used as a reducing agent.The conditions of ashing and colouration of phosphomolybdehum Blue,the measurement wavelength and the confidence of this meth od were also studied.
