Oil shale resorcinols - Effective reagents for nitrite. An algorithm for the concentration effect
An algorithm is deduced to describe the effects of nitrite and central cation concentrations on the optical density when nitrite is tested as a nitrosoalkylresorcinolate complex. The values of the apparent stability constant and molar extinction coefficient valid at the optimum pH found are estimated for cobalt tri-(4-nitroso-5-methylresorcinolate), cobalt tri-(4-nitroso-2,5-dimethylresorcinolate), iron(II) di-(4-nitroso-5-methylresorcinolate) and iron(II) di-(4-nitroso-2,5-dimethylresorcinolate).
