Abstract
In this study glucose reinforced Fe3O4@cellulose glyconanoparticles (MGN) were prepared using epichlorohydrin and amino acid (lysine and arginine) as a linker. Bacillus capturing capability of amino acid modified Fe3O4@cellulose was compared to the glucose reinforced system. Results showed enhanced bacterial capturing of MGN relative to amino acid modified particles. Bacterial capturing efficiencies were increased to 91% and 95% in the magnetic cellulose arginine-glucose (MCAG) and magnetic cellulose lysine-glucose (MCLG), respectively, which confirmed the role of synergism on microbial efficiency. Effective parameters on bacterial capturing efficiency including; solution pH, contact time, dosage of MGN and the presence of some anions were also investigated. Moreover, presented system was employed for bacteria capturing from river water, sea water and milk samples. The results showed that these nanocomposites have good performance to be used as reusable antimicrobial magnetic materials. The results showed that these nanocomposites have good reusability after three cycles of sorption and desorption which confirmed the efficiency of the system for bacterial removing from water solutions.
