磁性多壁碳纳米管对BPA的吸附特性

针对普通碳材料吸附BPA需要过滤或离心等复杂过程,将Fe3O4晶体沉积到多壁碳纳米管(MWCNTs)表面,合成饱和磁化度为23.3 emu/g的磁性多壁碳纳米管(MMWCNTs)以实现简便的固液分离.MMWCNTs对水相BPA的吸附是一个快速过程,饱和吸附量为14.9 mg/g.MMWCNTs对水相BPA的吸附过程△G为负值,是一个自发过程;△H为负值,是一个放热过程;△S为正值,是一个熵增过程.MMWCNTs对BPA的吸附具有物理吸附特征,MMWCNTs与BPA之间的相互作用力主要为范德华力.     

Characterization of ISO 14001 implementation

Environmental degradation caused by human activities is of concern to society, government, industry, companies, and the people who are able to enjoy improved lifestyles because of industrial activities. However, all of these parties also have a responsibility to support and conserve the environment and act responsibly toward the earth. This article, which includes a systematic literature review and draws upon the authors’ practical experience, summarizes the benefits, motives, and difficulties in implementing environmental management systems using the International Organization for Standardization's (ISO) 14001 framework.

Energy and Economic flow in homegardens in Subtropical Yunnan,SW China: A case study on Sanjia village

We studied the energy and economic flow of six types of homegardens in Sanjia village, SW China. Our study showed that the energy input of six types of homegardens averaged 99.11-175.65 x 10¹⁰J/ha, the energy output was 102.30-159.83 x 10¹⁰J/ha and the ratio of input/output ranged between 1:0.880-1:1.416. The ratios of input to output of home-gardens that prioritized cultivation of crops were higher than for homegardens that prioritized animal husbandry or other economic activities. The economic ratio of input/ output of six types of homegardens varied between 1:0.997-1:1.376 and the economic output ranged between 2480.0-10131.5 RMB/yr. We concluded that the homegarden systems of Sanjia village are high in the input and output of energy and cash flow, and can provide a basis for designing models of farm economy in rural subtropical areas.
