摘要：

By means of dual-wavelength beta-correction spectrophotometry, a metal chelate's stoichiometric ratio (gamma), practical molar absorptivity (epsilon(p)) and instability constant (K) have been deduced. The four reactions of iron(III) with Xylene Orange, 1-(2-pyridylazo)-2-naphthol, 4-(2-pyridylazo)resorcinol and Chromazurol S have been utilized, The results were satisfactory.
