摘要
A sensitive method for the determination of traces of P in Fe, Ni, Co, Cu and Zn is based on the formation of an ion-associate with molybdate and malachite green, whose absorbance is measured at 620 nm. The calibration curve is linear up to 0. 1 0-mu-g/ml; molar absorptivity is 2.7 x 10(5) l mol-1 cm-1. It was found that commonly coexisting elements did not interfere.
