Abstract
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

. In the range of 0.5 -
23.0 µkg manganese (II) Beer’s law is obeyed. The extraction-

methods of manganese determination have been worked out. The strangers
ions influence on determination of manganese (II) has been studied. To de-
termine amount of manganese in eggplant
the proposed method was applied
successfully.

1. Introduction
Manganese is a trace element essential for living organisms include plants as a
nutrient participates in photosynthesis, enzyme activation, carbohydrate meta-
bolism and phosphorylation [1].
Besides of this manganese is used as a very important hardening agent in steel
industry. That’s why it often requires to determinate the amount of manganese
in chemical, biological and environmental samples.
