Efficient Near-Infrared Light-Responsive Imprinted Polymers as Pipette
Miniaturization of samples pretreatment platform simplifies analytical tasks in separation science. Here, a novel pipet tip microsolid phase extraction (PT-MSPE) smart device for the selective extraction of dibutyl phthalate (DBP) in plastic toy and cup was designed. In particular, the NIR light-responsive molecularly imprinting polymers (NIR-MIPs) was prepared by introducing Fe3O4
Full article: Detection of dibutyl phthalate in food samples by
Because phthalate plasticisers cause great harm to the human body, they are prohibited from use in any food, medicine or health care products. As one of the common phthalate plasticiser, a method is urgently needed to detect the content of dibutyl phthalate (DBP) in food samples.
Determination of Phthalate Esters in Drinking
Some phthalates that have been found at different concentrations in bottled and sachet water are dimethylphthalate (DMP), diethylphthalate (DEP), dibutylphthalate (DBP), di-n-hexyl-phthalate,...
Risk Evaluation for Dibutyl Phthalate (1,2-Benzene
Dibutyl phthalate (CASRN 84-74-2) is a colorless to faint yellow oily liquid. The primary use for dibutyl phthalate is as a plasticizer, in adhesives and sealants, and paints and coatings.
Reference Method of Measurements of the Content
The article considers the problems of environmental pollution by phthalates and the impact of phthalates on human health. The article describes the process of developing a reference method of measurements (RMM VNIIM-243-01-2025) of the mass fraction of esters of ortho-phthalic acid (dimethyl phthalate, diethyl phthalate, di(n-butyl) phthalate, benzylbutyl phthalate, di(2-ethylhexyl) phthalate
- How is dibutyl phthalate (DBP) risk assessed?
- The systematic investigation and risk assessment of dibutyl phthalate (DBP) were performed using an ultrasensitive dual-signal immunoassay in Zhenjiang, Jiangsu Province. In this study, C-dots@H-MnO 2 nanohybrid were synthesized and labelled on the secondary antibody to generate fluorometric and colorimetric signals.
- Can dibutyl phthalate be determined using solid phase extraction and gas chromatography?
- The aim of the work described here was to develop and validate a method by which dibutyl phthalate may be subject to determinations using solid phase extraction and gas chromatography. Optimization of the chromatographic method was based on the selection of working conditions for both the chromatograph and the detector.
- Can polypyrrole be used to detect dibutyl phthalate?
- Electrochemical detection dibutyl phthalate An efficient approach that integrates a molecularly imprinted conducting polymer, polypyrrole (PPY) with a sensitive electrochemical impedance sensing platform for the quantification of dibutyl phthalate (DBP) was presented.
- Where is dibutyl phthalate (DBP) obtained?
- Chemicals Dibutyl phthalate (DBP) and dibutyl phthalate-d 4 (DBP-d 4) were obtained from Sigma-Aldrich (Sigma-Aldrich, St. Louis, MO, USA); GC grade hexane and benzyl benzoate (BB), Ultra pure acetone and methanol were purchased from Merck (Dramstadt, Germany).
- Can a dual-signal Elisa detect dibutyl phthalate (DBP)?
- Volume 425, 5 March 2022, 127991 A dual-signal ELISA for dibutyl phthalate (DBP) detection was developed. Attributed to the high C-dots loading of H-MnO 2, a good performance produced. DBP occurrence in aquatic environments and beverages were investigated. Compared with 2016, DBP pollution in waters has been improved.
- Which analytical methods are used in DBP investigation?
- At present, instrumental analytical techniques are considered to be the most commonly used methods for the exposure levels of DBP investigation, such as liquid chromatography tandem mass spectrometry (LC-MS/MS) (Li et al., 2021, Shin et al., 2020) and gas chromatography mass spectrometry (GC-MS) (Anh et al., 2021, Zhang et al., 2019).
