Synthesis and characterization of azine-functionalized zinc cation metal–organic frameworks nanostructures upon silk fibers under ultrasound irradiation, study of pores effect on morphine adsorption affinity

• We here present a textile for the removal and extraction of morphine from aqueous samples using Zn(II)-MOFs and silk fibers.
• The effects of sequential dipping steps in growth of Zn(II)-MOFs upon fibers were studied.
• XRPD analyses indicated that the prepared Zn(II)-MOFs upon fibers were crystalline.

Thin films of a three-dimensional porous Zn(II)-MOFs (TMU-4 and TMU-5) were deposited on surfaces of silk fiber via a stepwise manner under ultrasound irradiation. The Zn(II)-MOFs@fibers were studied for removal and extraction of morphine from aqueous samples and the effect of host-guest interaction on adsorption and desorption efficiency were evaluated. The effect of sequential dipping steps in growth of Zn(II)-MOFs@fiber has been studied. These systems depicted a decrease in the size accompanying a decrease in the sequential dipping steps.
