Abstract

A rapid and precise X-ray fluorescence method is proposed for the simultaneous determination of trace amounts of copper, lead and zinc in cements. The method is based on prior removal of iron by extraction with methyl isobutyl ketone from 6M hydrochloric acid, followed by collection of copper, lead and zinc on a membrane filter as their hexamethyleneammonium hexamethylenedithiocarbamate complexes to give a thin layer suitable for X-ray fluorescence measurement. The use of an internal standard (nickel) improves the precision for the determination of copper, zinc and lead.

L-Aspartic acid/L-cysteine/gold nanoparticle modified microelectrode for simultaneous detection of copper and lead
2012, Thin Solid Films

Owing to the potential danger to the environment and human, there is a growing need for monitoring of copper (II) and lead (II) in water environment. Many methods have been investigated for the detection of copper (II) and lead (II), such as atomic absorption spectroscopy [4,5], X-ray fluorescence [6,7], mass spectrometry [8,9] and electrochemical voltammetry [10,11]. Electrochemical voltammetry has been proved to be a particularly suitable method for on-site determination of copper (II) and lead (II), due to its properties such as small in size, simple, portable, reliable and low-cost.
This paper presents an electrochemical microsensor for simultaneous detection of copper (II) and lead (II) using an l-aspartic acid/l-cysteine/gold nanoparticle modified microelectrode. The microelectrode was fabricated by Micro Electro-Mechanical System technique. The complex of gold nanoparticles (AuNPs) and amino acid with carboxyl group was used as the selective ligand for metal ions. The microelectrode was firstly modified with AuNPs to increase the sensitive area of the working electrode. Subsequently, the AuNPs/gold electrode was modified with l-cysteine and then covalently linked with a monolayer of l-aspartic acid using glutaraldehyde. Electrochemical analysis of metal ions was achieved by using square wave voltammetry without stirring. The microsensor exhibited an excellent linear range from 5 μg L^− 1 to 2000 μg L^− 1 with the limit of detection of 1 μg L^− 1. This metal ion detection method based on l-aspartic acid/l-cysteine/gold nanoparticle modified microelectrode is simple, sensitive and it could be used for electrochemical analysis of copper (II) and lead (II).
Detection of trace levels of lead in aqueous liquids using extractive electrospray ionization tandem mass spectrometry

Therefore, it is useful to develop novel approaches for the fast, sensitive, and reliable determination of lead in aqueous liquid samples, not only for environment assessment but also for clinical significance. Currently, representative techniques for lead detection include colorimetric assay, atomic absorption spectrometry (AAS), atomic emission spectrometry (AES), electrochemistry methods, biosensors, nuclear magnet resonance, and mass spectrometry [24–27]. Inductively coupled plasma mass spectrometry (ICP-MS) has been widely used to detect lead in biological fluids, tissues, environmental samples, and oils [28–35].
A sensitive approach, based on semi-quantitative measurement of the characteristic fragments in multi-stage extractive electrospray ionization mass spectrometry (EESI-MSⁿ), was developed for fast detection of trace levels of lead in aqueous liquids including mineral water, lake water, tap water, energy drinks, soft drinks, beer, orange juice, and tea. A disodium ethylene-diamine-tetraacetic acid (EDTA) aqueous solution was electrosprayed to produce negatively charged primary ions which then intersected the neutral sample plume to generate anions of EDTA-Pb(II) complexes. The charged EDTA-Pb(II) complexes were characterized with multistage collision induced dissociation (CID) experiments. The limit of detection (LOD) using EESI-MS³ was estimated to be at the level of 10^–13 g/mL for directly detecting lead in many of these samples. The linear dynamic range was higher than 2 orders of magnitude. A single sample analysis could be completed within 2 min with reasonable semi-quantitative performance, e.g., relative standard deviations (RSDs) for deionized water were 4.6–7.6% during 5 experimental runs (each of them had 10 repeated measurements). Coca-cola and Huiyuan orange juice, representative beverage samples with complex matrices, generated recovery rates of 91.5% and 129%, respectively. Our experimental data demonstrated that EESI-MS is a useful tool for the fast detection of lead in various solutions, and EESI-MS showed promises for fast screening of lead-contaminated aqueous liquid samples.
Analysis of cement and cement raw meal by atomic absorption spectrophotometry using a new fusion agent
1995, Talanta
A new fusion agent is proposed for the analysis of cement and cement raw meal using AAS. In the described method, 0.8 g of the fusion agent, consisting of equal portions of oxalic acid, lithium carbonate and lithium tetraborate, was mixed with 0.2 g of the sample, and the mixture was fused for 10 min at 925°C in a platinum crucilbe. The fusion cake was dissolved with dilute hydrochloric acid (1 + 10) and diluted to 500 ml for the determination of Si, Al, Fe, Ti, Na and K expressed as SiO₂, Al₂O₃, Fe₂O₃, TiO₂, Na₂O, and K₂O respectively. For the determination of Ca and Mg (expressed as CaO and MgO respectively), 10 ml of the previous sample solution were mixed with 4 ml of 6% (m/v) lanthanum nitrate solution and the solution was diluted to 100 ml. The method was found to have good accuracy and precision. The time required to determine the eight elements was around 80 min for each sample.
