Abstract (300 words maximum)

Design of CF-MOF@AgNPs Composite Materials to Detect Microplastic: SERS Detection

Elohor Okoko, and Bharat Baruah*

Plastics in micro- and nano-size have become a significant pollutant in our environment because of its non-biodegradability. The purpose of the research is to devise a way to detect nano-plastics, which are very much invisible plastics. Metal-organic framework (MOF), UiO-66-NH2 was embedded into the cotton fabric (CF) following a solvothermal method to create a CF-MOF composite. We synthesized silver nanoparticles (AgNPs) in water using a mixture of cetyltrimethylammonium bromide (CTAB), nonyl amine (NA), silver nitrate, and ascorbic acid. Further, the CF-MOF was dip-coated with AgNPs to fabricate CF-MOF-AgNPs composite. Nano plastics are created by breaking bulk plastics mechanically. Surface-enhanced Raman Scattering (SERS) technique is used to detect nano-plastic in the presence of CF-MOF-AgNPs. The fabricated composite material, CF-MOF-AgNPs, was characterized by FTIR, XRD, and SEM.
