Abstract

Formaldehyde is one of the substances causing sick for human being.Small doses of formaldehyde can cause a variety of symptoms of physical discomfort. High dose and long time exposure to formaldehyde will increase the probability of cancer. However, the content of formaldehyde in the newly renovated room or near the new furniture is very high. To solve the formaldehyde, this paper developed a new kind of sodium carboxymethyl cellulose/carboxyl graphite oxide (CMC/GO-COOH) scaffold via a lyophilization method. Then, this synthetic scaffold was characterized by Fourier transform infrared spectroscopy (FT-IR), scanning electron microscope (SEM), hydrophilic test, mechanical property and in vitro detoxification test. There were covalent bonding and hydrogen bonding in the scaffold, indicating the strong interactions between CMC and GO-COOH. There were interconnected network in the structure of synthesized scaffold. The mechanical test suggested that the CMC/GO-COOH scaffold had excellent mechanical strength, which was 3.41±0.12MPa with shrink of 25%. Furthermore, the adsorption of CMC/GO-COOH to formaldehyde wereup to 10.97±1.84 mg/g. The resulting CMC/GO-COOH scaffold held great potential for adsorbing formaldehyde.
