Epichlorohydrin (EPI) was used as crosslinking agent, and β-cyclodextrin (β-CD) was used to modify biochar (BC). The prepared modified biochar materials were labeled with β-CDBC, β-CDBC-Na, β-CDBC-CA and β-CDBC-H, respectively. The infrared spectrum, X-ray diffractometer, scanning electron microscope and specific surface area of the four modified materials were tested. The results showed that the C-O stretching vibration peak at 1020 cm<sup>−</sup><sup>1</sup> of the modified materials was slightly offset compared with that of biochar. The characteristic absorption peaks of XRD pattern decrease obviously at 2θ = 26.7˚ and 29.5˚. It can be obviously observed on the electron microscope image that the surface is loaded or formed clathrates, and BET data and graphs also show that the specific surface area of the modified biochar is larger. Therefore, β-cyclodextrin successfully modified biochar and formed clathrates on the surface of biochar or was loaded in the pore structure of biochar, especially β-CDBC-CA achieved better modification effect. Because biochar and β-cyclodextrin raw materials are cheap, easy to prepare and green, and less prone to secondary pollution, it has a good advantage in environmental governance.展开更多

For the pollution problem in China’s textile and garment industry, the author particularly analyzes the pollution of the textile and garment industry mainly occurred in the process of textile and clothing production and sales in this article. Finally, the author puts forward detail measure to control the pollution from the two aspects and advocates the concept of low-carbon environmental protection and green lifestyle. The low-carbon environmental protection has become a phenomenon in Textile and Apparel.展开更多

Since excessive exposure to the sun and frequent sunburns predispose to melanoma, one wonders if green tea can also protect against melanoma.展开更多
