Development of an Analytical Method for Dibutyl Phthalate
Dibutyl phthalate (DBP) is a phthalic acid ester and is widely used in polymeric products to make them more flexible. DBP is found in almost every plastic material and is believed to be persistent in the environment. Various analytical methods have been used to measure DBP in different matrices. Con
Investigation and risk assessment of dibutyl phthalate in a
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.
Development of an Analytical Method for Dibutyl Phthalate
This method was sufficiently sensitive to detect di-(2-ethylhexyl) phthalate, dibutyl phthalate (DBP) and diethyl phthalate (DEP) in two groups of raw cow milk samples (cow milk samples collected
Preparation method of dibutyl phthalate (DBP) - Google
A preparation method for dibutyl phthalate, comprises the following steps: One, esterification step 1, proportioning raw materials Phthalic anhydride butanols sulfuric acid activated carbon...
- 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.
- 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 surrogate analyte be used to determine DBP in hexane samples?
- Standard addition method or using artificial matrices reduce the precision and accuracy of the results. In this study a surrogate analyte approach that is based on using deuterium labeled analyte (DBP-d4) to construct the calibration line was applied to determine DBP in hexane samples.
- How to determine DBP in different matrices?
- Various analytical methods have been applied to determine DBP in different matrices. Utilizing DBP as a plasticizer or dispersing agent in various products makes it to be easily detectable in almost all of the analytical grade solvents and materials that are commonly used for extraction and cleanup procedures in analytical methods.
- What is the precision of recovery results for DBP?
- Recovery results for DBP. Precision can be expressed in terms of relative standard deviation (R SD). This was to above. Table 4. Precision of the method. the level of sensitivity of the equipment used clear. T he limit of detection (LOD) was a peak about 10 times a s high as the noise height . analysis has been developed and validated.
- What is the most important challenge in DBP analysis?
- Considering the ubiquitous nature of DBP, the most important challenge in DBP analyses is the contamination of even analytical grade organic solvents with this compound and lack of availability of a true blank matrix to construct the calibration line.
