INVESTIGATION OF COMPLEX FORMATION OF NICKEL(II) WITH 2,6-DIETHYL-4-METHYLPHENOL AND AMINOPHENOL

Abstract

Nickel (II) is a biologically active metal. It is established that excessive "technogenic" entry of nickel compounds into the body has a toxic effect on metabolism, causes morphological changes in the cell, and thus has a carcinogenic effect on it. Nickel plays a major role in biological processes occurring in the body, and is an indicator of some diseases. At the same time, transition metals are toxic elements and their presence in the air and natural waters is regulated at the MPC level.

The presented work is dedicated to the spectrophotometric study of different ligand complexes (DLC) Ni(II) with 2,6-dithiol-4-methylphenols (DTMF) and hydroxyl-containing hyd­rophobic amines (aminophenols). From aminophenols (АP) used 2 (N,N-dimethyla­mino­methyl)-4-methylphenol (АP₁), 2(N,N-dimethylaminomethyl)-4-chlorophenol (АP₂), 2(N,N-dimethyla­minomethyl) -4-bromophenol (АP₃).
