Abstract

A new Schiff base complex of [UO2L(C2H5OH)(H2O)3]NO3 (HL=4-(2-hydroxy-naphthalen-1-ylmethyleneamino)-antipyrin) composition has been synthesized and characterized by elemental analysis, IR, UV and molar conductance. The thermodecomposition kinetics of the complex was investigated under non-isothermal conditions. TG and DTG curves indicate that the complex decomposes in five steps. The kinetics of the first step was calculated by a combination of Achar differential and Coats-Redfern integral methods. The kinetic equation was determined.
