STUDY ON THE COMPLEX FORMATION BETWEEN N-PROPYLSALICYLIDENE BASED ON SILICA AS ION EXCHANGER AND SOME TRANSITION METAL IONS
N-propylsalicylidene based on silica as ion exchanger (IE) was used for the separation by complexation of Mn2+, Co2+, Ni2+, Cu2+, Hg2+, Cr3+, Fe3+, and UO22+ from their parent solutions. IE and its metal complexes are characterized by elemental analysis, electronic and infrared spectra, in addition to thermal analysis in atmospheric pressure. The mode of chelation and the proposed geometric str...
متن کاملV). Separation Processes-solvent Extraction/ Ion Exchange for Metal Ions
In the hydrometallurgical processing of complex ores/ concentrates/ secondaries/ wastes, the solutions containing different non-ferrous metals are obtained during teaching the materials in acidic, ammoniacal or alkaline lixiviants. The spent solutions and effluents are also generated in different process industries and contain metallic values. Their discharge in the sewage or river is major con...

متن کاملfabrication of new ion sensitive field effect transistors (isfet) based on modification of junction-fet for analysis of hydronium, potassium and hydrazinium ions
a novel and ultra low cost isfet electrode and measurement system was designed for isfet application and detection of hydronium, hydrazinium and potassium ions. also, a measuring setup containing appropriate circuits, suitable analyzer (advantech board), de noise reduction elements, cooling system and pc was used for controlling the isfet electrode and various characteristic measurements. the t...
Charge Exchange Ions Produced by an Ion Propulsion System
In this paper, we present observations of charge exchange ions generated by the ion propulsion system (IPS) on the Deep Space One (DS1) spacecraft . We show that the equilibrium flux of charge exchange ions correlates well with IPS thrust levels, but that the flux requires approximately 4 hours to build up to equilibrium value after the start of IPS operation. In time of flight mass spectra, th...
