| Abstract: | A
novel chitosan derivative has been synthesized by the dispersible nano-SiO2
(DNS), succinic anhydride, and chitosan in two steps. The structure and
morphology of the new material are characterized by fourier transform infrared
spectroscopy and scanning electron microscope. Thermogravimetric studies show
improvement in thermal character. The effects of initial pH, adsorption time, adsorbent dosage and temperature have also
been studied. The adsorption equilibrium data are fitted with the Langmuir
isotherm (R = 0.999), which reveals that the maximum capacity for monolayer
saturation is 3.9108 mmol·g-1. Chitosan derivative shows stronger
adsorption than chitosan. The optimal adsorption conditions of chitosan
derivative are found to be pH 5.0,
time 4 h, and adsorbent dose 0.1 g respectively. |
