Abstract
The individual determination of Be(II), Mg(II) or Ca(II) by convention al spectrophotometry and simultaneous determination of Mg(II) and Ca(I I) in mixtures by first-derivative spectrophotometry are possible at t race levels, using emodin (1,3,8-trihydroxy-6-methylanthraquinone) as spectrophotometric reagent. Interference from other metal species, app lication of these methods to rock samples and statistical analysis of the results are discussed.
