Synthesis and characterization of new azo-linked Schiff bases and their cobalt(II), copper(II) and nickel(II) complexes
Azo compounds were prepared by the reaction between benzenediazonium chloride and 4-amino-5-hydroxy-2,7-naphthalenedisulfonic acid monosodium salt under alkaline conditions. Two new azo-linked Schiff base ligands, ...
Electron paramagnetic resonance of organic and inorganic centers in ?-irradiated natural sepiolite minerals
Natural sepiolite minerals and their ?-irradiated forms were investigated by electron paramagnetic resonance (EPR) at room temperature and at 113 K. The EPR signals in powders of natural sepiolite were observed due to ...
The Effects of composted poultry wastes on nitrogen mineralization and biological activity in a silt loam soil
Poultry manure or its compost are rich in plant nutrients and have a special potential to meet N and P requirements of agricultural plants. A laboratory study was carried out for 84 days at 30°C to asses the effect of ...
