Abstract
Combination effects of diverse elements in the presence of lanthanum and barium were studied, and both lanthanum and barium were found to be suitable elements for supressing the interference from diverse elements. Procedures for atomic absorption spectrophotometric determination of magnesium in zinc base alloys and silicate minerals have been established and good results were obtained by using the proposed method. The determination limit was found to be 0.01 ppm, being the concentration corresponding to give 1% absorption.
