Lead preconcentration by solid phase extraction using oxidized carbon xerogel and spectrophotometric determination with dithizone
(Elsevier Science, 2016-09)
The proposed methodology is based on the preconcentration of Pb2+ on oxidized carbon xerogel, a porous material of low density and high surface area. Adsorbed Pb2+ was eluted with HCl, followed by complexion with dithizone ...
Determination of lead in drinking water by ICP-AES with ultrasonic nebulization and flow-injection on-line preconcentration using an amberlite XAD-16 resin
(Taylor & Francis, 2002-10)
An on-line lead preconcentration and determination system implemented with inductively coupled plasma atomic emission spectrometry (ICP-AES) associated to flow injection (FI) with ultrasonic nebulization (USN) was studied. ...
Observational Study of the Relationship Between the Level of Lead and Hemoglobin in Women from Mining Centers in Huancavelica - Peru at More Than 3900 Mas L May, 2022
(Seventh Sense, 2023)
The objective of this study was to determine the relationship between the level of lead in blood and the level of hemoglobin in women of childbearing age who live under the influence of mining centers in the Huancavelica ...
Quantitative analysis of lead in polysulfide-based impression material
(ABM, ABC, ABPol, 2007-06)
Permlastic® is a polysulfide-based impression material widely used by dentists in Brazil. It is composed of a base paste and a catalyzer containing lead dioxide. The high toxicity of lead to humans is ground for much ...
A sensitive spectrophotometric method for lead determination by flow injection analysis with on-line preconcentration
(Elsevier Science, 2004-12)
A new flow injection (FI) system for the determination of Pb(II) at trace level with a preconcentration step and spectrophotometric detection is proposed. It is based on preconcentration of lead ions on chitosan and ...
