Abstract

The synthesis chitosan linked by methylene bridge-Schiff base of 4,4-diaminodiphenyl ether-vanillin (modified chitosan adsorbent) has been studied. The aims of this research were modification of chitosan with Schiff base of 4,4-diaminodiphenyl ether-vanillin and formaldehyde and its application as antibacterial agent after used as an adsorbent of Zn(II) ion. Characterization of modified chitosan adsorbent was conducted using FTIR spectroscopy. Process of adsorption were conducted at 0.15 g of modified chitosan adsorbent reacted by concentration of Zn(II) ion solution (pH 6, 150 mg/L, 50 mL), contact time at 150 min. and at room temperature (280C). Modified chitosan adsorbent after reacted by Zn(II) ion solution as antibacterial agent with paper disk method. The result showed that chitosan can be modified with Schiff base of 4,4-diaminodiphenyl ether-vanillin and formaldehyde to form chitosan linked methylene bridge and Schiff base of 4,4-diaminodiphenyl ether-vanillin. Antibacterial of chitosan and modified chitosan adsorbent were higher than modified chitosan adsorbent after reacted by Zn(II) ion. Keywords : modified chitosan, antibacterial agent

Abstract

The synthesis of modified chitosan has been studied. The aims of this research were modification of chitosan with ZnO nanoparticle to form chitosan-ZnO nanoparticle and its application as antibacterial agent of Staphylococus aureus. Characterization of modified chitosan was conducted using FTIR spectroscopy and X-Ray diffractometer. ZnO nanoparticle was synthesized by leaf extract of Sirih hijau (piper betle L) and zinc acetate dihydrate. Modified chitosan was synthesized by chitosan and ZnO nanoparticle. Modified chitosan solution can act as antibacterial agent with paper disk method. The result showed that chitosan can be modified with ZnO nanoparticle and detected at wave number of 3427 cm−1. The crystalline size of ZnO nanoparticle is 16.47 nm. The average inhibition zone of chitosan-ZnO nanoparticle at concentration 10.000, 5.000 and 2.500 ppm are 28.87 ± 0.4 ; 24.93 ± 0.15 and 19.35 ± 0.3 mm respectively.

Abstract

The biosynthesis of CuO nanoparticles was studied. The aims of this research were biosynthesis CuO nanoparticles from Cu2+ion solution and leaves aquoeus extract of sweet star fruit and its in vitro study as antibacterial agent of Escherichia coli. CuO nanoparticles was characterized using FTIR spectroscopy and X-Ray diffractometer. CuO nanoparticles was synthesized by reaction between Cu2+ion solution and leaves aquoeus extract of sweet star fruit. Paper disk method was used as the application of the suspension of CuO nanoparticles. The result showed that Cu-O groups detected at wave number of 503, 619, 767 and 821 cm-1. Diffractogram of CuO nanoparticles had sharp and narrow diffraction peaks. The crystallite size of CuO nanoparticles was 4.25 nm. The average inhibition zone of CuO nanoparticles at concentration 10.000, 7.500, 5.000 and 2.500 ppm was 17.43 ± 1.81 ; 15.73 ± 0.40 ; 14.50 ± 2.96 and 9.67 ± 0.28 mm respectively.
