Abstract

âº We introduce a new SPME fiber preparation method based on aluminum grafting process. âº Grafted Al-fused silica was applied for extraction of NDELA from cosmetic products. âº Al provides acidic sites which can effectively interact with basic sites of NDELA. âº The method is more simple, fast and efficient than other developed methods.
