Result and discussion This chapter includes spectroscopic (IR , UV- Vis , Mass and ESR) and elemental studies of the ligands and its metal complexes were reported. The electronic spectral data confirmed octahedral structures for The chelates. The ESR spectra for Cu(II) chelates show axial typ (dx 2-y 2) ground state with covalent bond character. For application as foliar fertilizer The synthesized metal chelates were evaluated as plant growth promoter and productivity ability of the organically chelated metal nutrients on pepper plant. The growth characters like plant height, leaves area, number of flowers, number of branches per plants and total yield per Plant was determined after last harvest. . The antimicrobial activity revealed the compounds recorded an activity against Candida albicans fungi . In contrary, it was found that most compounds exhibit antibacterial activity against the other tested types of microbes. complex (3) and (12) represented the most sensitive complex against Candida albicans fungi, whereas complex (12) recorded moderate activity against Escherichia coli and Streptococcs pneumonia. The catalytic decomposition of H2O2 in presence of [Cu(II)Fulvate] complex as a catalyst, depends upon the concentration of the catalyst , temperature and slowed with high concentrations of H2O2.The rate of the reaction is of pseudo first order with respect to the concentration of the catalyst and temperature . The proposed mechanism involves reduction of Cu(II) to Cu(I), during the slow rate determining step. |
