Abstract
A simple, sensitive, facile and low cost methodology, combined with flame atomic absorption spectrometry (FAAS), was employed to evaluate the selective separation and preconcentration of Pd(II) ions in environmental samples by using a triazole derivative as an organic coprecipitating agent without a carrier element. The developed method was systematically investigated in different set of experimental parameters that influence the quantitative recovery of Pd(II) ions. The accuracy of the method was tested by analyzing certified reference material and spike tests. The developed coprecipitation procedure has been applied to road dust, anodic slime, industrial electronic waste materials and water samples to determine their Pd(II) levels.
Highlights
Palladium, a precious metal, is widely used in the jewelry industry and in the production of many different kinds of electronics such as semiconductors found in personal computers, cellular phones and several electronic control devices [1,2,3]
This paper describes an approach to develop a sensitive, safe, rapid, simple and low cost preconcentration/matrix separation method based on carrier element free coprecipitation (CEFC) for the accurate determination of Pd(II) ions level in environmental and industrial samples by flame atomic absorption spectrometry (FAAS)
The accurate and precise determination of Pd(II) ions in industrial and environmental solid and liquid samples based on CEFC method has been investigated
Summary
A precious metal, is widely used in the jewelry industry and in the production of many different kinds of electronics such as semiconductors found in personal computers, cellular phones and several electronic control devices [1,2,3]. This paper describes an approach to develop a sensitive, safe, rapid, simple and low cost preconcentration/matrix separation method based on CEFC for the accurate determination of Pd(II) ions level in environmental and industrial samples by FAAS. In the present study HAMT was used for the first time as an organic coprecipitating agent for selective separation and preconcentration of Pd(II) ions.
