Cellulose fiber-based yarn development for capturing estrogen residues from aqueous matrices with MP-SPR

Application Note #165

 

Figure 1. CNF coated with chitosan by adsorption. TO-βCD is conjugated to chitosan with EDC-NHS chemistry. TO-βCD captures EE2 from water.

In-situ preparation of chitosan and cyclodextrin-functionalized cellulose fiber yarns and capture of the synthetic estrogen hormone 17α-ethinyl estradiol (EE2) from water was investigated to address waste water purification. The thickness of functionalized chitosan and cyclodextrin layers were determined. The effectivity of the hormone capture was determined by determining the thickness of adsorbed EE2 layer.
