Improvement of PVC compound plasticizer extraction process
The Soxhlet method in extracting plasticizers from PVC compounds presents various areas for improvement, such as the amount of solvent used, the time required in the process, and its costs. This study proposes replacing the Soxhlet method with the ultrasound-assisted method to reduce the time, costs, and amount of solvent used in plasticizer extraction. It also proposes using solvent recovered
Accelerated Solvent Extraction of Plasticizers from Polyvinyl
solvent extraction or Soxhlet conditions described above. AN70640_E 07/13S Application Note 336 Method Validation When developing extraction methods, one way to validate extraction efficiency is to re-extract the same sample and check for remaining analytes. The Dionex ASE system allows the analyst to automate re-extraction for easy method
Analytical methods for the determination of DEHP plasticizer
In the study by Wang et al., the simple room temperature extraction using chloroform was found to be the most efficient method for extracting alternative plasticizers like DEHA [42]. Polymer dissolution is also a solid–liquid extraction procedure that may be used to extract alternative plasticizers from medical device samples. The whole
Improvement of PVC compound plasticizer extraction process
The proposed method yields 96 % of plasticizer extraction, a decrease from 360 to 60 minutes in the extraction process, and a decrease from 150 to 100 ml in solvent use. Complemented by the...
