“…Wet digestion can be carried out in open glass vessels (digestive tube) at atmosphere pressure or in closed Teflon beakers, perfluoroalkoxy tanks at high pressure. These vessels contained sample and reagent mixtures were subjected to heat on a hot plate or an oven at 70–130°C for 1–15 h . Some products such as eye shadows, foundations, and mineral mask powders contain a large amount of minerals (mica, titanium dioxide, and zinc oxide), which are hardly dissolved in common acids, but can be rapidly decomposed using a small volume of hydrofluoric acid in Teflon vessel .…”

The widespread applications of cosmetics in modern life make their analysis particularly important from a safety point of view. There is a wide variety of restricted ingredients and prohibited substances that primarily influence the safety of cosmetics. Sample preparation for cosmetic analysis is a crucial step as the complex matrices may seriously interfere with the determination of target analytes. In this review, some new developments (2010-2016) in sample preparation techniques for cosmetic analysis, including liquid-phase microextraction, solid-phase microextraction, matrix solid-phase dispersion, pressurized liquid extraction, cloud point extraction, ultrasound-assisted extraction, and microwave digestion, are presented. Furthermore, the research and progress in sample preparation techniques and their applications in the separation and purification of allowed ingredients and prohibited substances are reviewed.

“…23 Therefore, the reported methods were suitable for Cd determination in a lab, but could not be applied to detection in the elds. To resolve the conicts between the complicated digestion methods and the need for eld-portable detection equipment, we established a rapid pretreatment method for Cd in rice using diluted acid without microwave 24 or ultrasound 25 assistance, and it could extract Cd from rice at room temperature within 5 min. 26,27 Sequential extraction has been used to identify the chemical forms of Cd in roots, leaf sheaths, and leaves of both types of rice plants, and 0.6 M of HCl has been used to extract cadmium oxalatefrom frozen shoot and root tissues.…”

“…A series of analytical methods for trace determination of copper such as solid‐phase extractive spectrophotometry, atomic absorption spectroscopy, inductively coupled plasma mass spectrometry (ICP‐MS) and X‐ray fluorescence have been reported in literature . However, several shortcomings are linked with most of these reported methods.…”

This study reports a highly sensitive electrochemical sensor based on Bi film modified glassy carbon electrode (BiF/GCE) for total determination and speciation trace concentrations of copper(II) ions in environmental water samples. Square wave‐adsorptive anodic stripping voltammetric (SW‐ASV) experiment was performed for monitoring selective accumulation of copper(II) with reagent 3‐[(2‐mercapto‐vinyl)‐hydrazono]‐1,3‐dihydro‐indol‐2‐one (MHDI) at pH 9–10. The mechanism of the electrode reaction of Cu2+‐MHDI complex was safely assigned. The sensor exhibited a wide linear range (3.22×10−9–2.0×10−7 mol L−1) with lower limits of detection (LOD) and quantitation (LOQ) of 9.6×1−10 and 3.22×10−9 mol L−1, respectively (R2=0.9993). The proposed sensor exhibited interference from active metal ions e. g. Cd, Hg. The performance of the proposed method was compared successfully with most of the reported methods and comparable efficiencies were obtained. The analytical utility of the proposed SW‐ASV method has been successfully validated for trace analysis of copper(II) in environmental water samples. The method offers a precise, accurate approach with good reproducibility, robustness, ruggedness, and cost effectiveness.
