Determination of opiates in urine samples using a composite of covalent organic framework and polypyrrole as a sorbent for microextraction in a packed syringe combined with HPLC/UV

This study aimed to develop microextraction in a packed syringe (MEPS) method for the determination of the three opiates in urine samples. Covalent organic framework-polypyrrole- cetyltrimethylammonium bromide (COF-PPy-CTAB) nanocomposite, as an appropriate and highly efficient adsorbent, was synthe...
