Abstract
Chitosan/Alginate Nanoparticles (CANPs) were produced via microemulsion method. SEM images captured that CANPs has rough, irregular, and porous surfaces. The particle sizes were in the range of 1-15 nm with an average diameter of 8.31 nm. CANPs were applied for trace metals removal. Optimum adsorption capacity of Zn(II) and Cu(II) were 8.144 and 5.582 mg g-1, respectively. Kinetic studies show that the adsorption of Zn(II) and Cu(II) onto CANPs fitted pseudo second order model. Isotherm studies determined that the sorption followed Dubinin-radushkevich model. Zn(II) adsorbed CANPs (Zn/CANPs) and Cu(II) adsorbed CANPs (Cu/CANPs) were investigate their antibacterial activity againts E. coli and S. aureus. Zone of Inhibition (ZOI) of Zn/CANPs were 19.3 mm (E. coli) and 17.5 mm (S. aureus). ZOI of Cu/CANPs were 14.17 mm (E. coli) and 10.75 mm (S. aureus). The results revealed that CANPs were a promising bifunctional material for metals removal and has good antibacterial activity.
