Ion Exchange for Recovery of Precious Metals
ith the rapid rise that has occurred in the prices of precious metals during the past few years, recovery of even minute amounts of theseelements has become of greater interest to metal finishers. Although precious metals are recovered easily from concentrated solutions by reduction and precipitation or electrolysis, solutions containing a few parts per million aredifficult to handle by these m...
متن کاملIon Exchange Column Performance Model for Separation of Zr(IV) and Hf(IV) in Elution Process
A mathematical model of sorption of Zirconium and Hafnium cations mixture and elution of these ions from a cation exchange resin bed is developed. Sulfuric acid is selected as the eluent for selective separation of Zr and Hf in a packed bed of Dowex cation exchange resin. The column model is a dispersed plug flow model,and assumed to consist of randomly packed synthetic and spherical resin ...
متن کاملNitrogen Isotope Separation by Ion Exchange Chromatography
Enriched stable isotopes of many elements have been widely used in many aspects and such isotopes have been primarily used as the tracer for agricultural and biochemical studies and the availability of the isotopically labeled compounds have been now extensively increasing. Chemical exchange separation of isotopes is based on the equilibrium fractionation of isotopes between two phases, ion exc...
متن کاملRapid Determination of Lead in Urine by Ion Exchange.
For routine screening of employees in the lead industry, a method for determination of urinary lead was developed in which this element is removed from urine by means of a chelating agent, eluted, and determined by a modified dithizone method. The method gives values which are about 5% below those obtained by the wet ashing technic, with a precision of ± 2.1% in the range of 2-15 jig. of lead p...
متن کاملGenotoxicity studies of heavy metals: lead, bismuth, indium, silver and antimony.
OBJECTIVES Many kinds of heavy metals are used in industry; thus, it is important for us to clarify their toxicity. For example, lead, which is a component of solder, is notorious for its neurotoxicity, and substitute materials have been sought for many years. Therefore, we examined the genotoxicity of lead and also those of metallic bismuth, indium, silver and antimony which are possible subst...
