Mussel Shells

CaO samples prepared from calcining the powdered waste shells at 1300°C for 4 h were tested the efficiency of humidity adsorption. The samples were characterized via X-ray diffraction (XRD) and Fourier transform infrared analysis (FT–IR) to identify the characteristic of CaO after humidity adsorption test. The results indicate that duck eggshells are highest capable of humidity adsorption while hydration rate of chicken eggshells is rather equal to that of cockle shells, and lowest hydration rate was found with sample prepared from Mussel shells. Therefore, we can conclude that the waste shells are suitable to be use as humidity adsorbent for commercial in the future

Effect of aeration treatment on Methylene Blue (MB) removal using TiO2-Zeolite has been investigated. The TiO2-Zeolite was prepared by mixing activated zeolite and TiO2 in absolute ethanol. This composite was characterized using Fourier Transform Infrared (FT-IR) and X-Ray Diffraction (XRD). The MB removal was monitored spectrophotometrically. The effect of contact time, composite mass, and aeration treatment on MB removal was observed. Characterization results showed that there was interaction between TiO2 and SiO/AlO of zeolite. The observation of aeration treatment using oxygen exhibited significant improving on MB removal.

Ultraviolet Absorbers

2-hydroxy-4-glycidyl ether benzophenone(HGEBP) is synthesized with 2,4-dihydoxy- benzophenone(UV-0) and epichlorohydrin(ECH) as starting material, then a series of chitosan (CS) based novel ultraviolet absorbers (CS-g-UV-0) are synthesized by the reaction of chitosan with HGEBP in isopropylcarbinol in the presence of sodium hydroxide. The products(CS-g-UV-0) are characterized by means of Fourier transform infrared spectra (FT-IR), X-ray diffraction (XRD), and UV spectrophotometer. The results of UV absorption show that anyone of the grafted products has a strong ultraviolet absorption area ranging from 280nm to 350nm and the maximum absorption peak presents at 291 nm. It is found that the grafted products could improve the moisture-absorption and moisture-retention property with the increase of G% values.
