This study deals with the synthesis and study characterization of two sets (3a-g) and (6a-g) as tri-substitution derived from 1,3,5-trihydroxybenzene (Phluroglucinol).The first series (3a-g), scheme 1 was synthesized from the reaction of 1,3,5trihydroxybenzene with p-alkoxybenzoyl chloride.
A new Schiff base polydentate ligand (tetra Aza) has been prepared: 2,6-bis-(Azomethine ethyl Azomethine ortho phenol) 4-methyl phenol.
Synthesis was carried out by two steps of condensation, first by the condensation of 2,6-diformyl-4-methyl phenol and ethylenediamine in the mole ratio (1:2) under nitrogen atmosphere.
The photodegradation and degradation of two azo group containing dyes namely; methyl orange (MO) as mono azo model and congo red (CR) as di azo model moieties, have been investigated, throughout this thesis, in aqueous medium. Three different nitrogen content (2.5%, 5% and 7%) laboratory synthesized doped anatase TiO2 nano particles (N-TiO2) have been employed as a photocatayst utilizing visible light illumination. The N-TiO2 photocatalysts have been characterized employing several spectroscopic and electronic tools encompassing.
