摘 要:4,7-diphenyl-1,10-phenantroline from heterocyclic diamines and alizarine yellow R from chromogenic reagents have been used for spectrophotometric determination of manganese in the form of heteroligand manganese complex. The complex formation and extraction condition, physical-chemical and analytical characteristics of this complex have been established. 5.5 - 11.0 pH range is observed as complex formation pH range. Extraction and stability constants were accordingly found as Kext = 8.32 × 1014 and lgβK = 7.2 ± 0.1. Molar absorptivity is ε = (2.27± 0.08) × 104 l·g-1·cm-1. In the range of 0.5 - 23.0 μkg manganese (II) Beer’s law is obeyed. The extraction-photometric methods of manganese determination have been worked out. The strangers ions influence on determination of manganese (II) has been studied. To determine amount of manganese in eggplant the proposed method was applied successfully.4,7-diphenyl-1,10-phenantroline from heterocyclic diamines and alizarine yellow R from chromogenic reagents have been used for spectrophotometric determination of manganese in the form of heteroligand manganese complex.
