The present work addresses the students in chemistry, chemical
engineering of the environment, as well as the specialists in chemistry
of the phosphorus and the organophosphate compounds, in Hydrometallurgy
both at the industrial level and at the level of the scientific
research. This work aims to be a guide for the chemistry of the agent's
complexants of types phosphonic & aminophosphonic acids, consisted
widely used in the liquid-liquid extraction for the extraction of metals
and rare earths, in the proceeding of ores and in the aqueous effluent
treatments for the recovery and the valuation of rare earths, N-C-P in
medicinal chemistry, pesticides/herbicides and water-decontamination
systems, organometallic complexes: MOF, gas absorption, proton
conductivity and Magnetic shielding tensors.
