球形纤维素吸附剂的研究现状及发展趋势

Research on the Spherical Cellulose Adsorbents:Actuality and Trend

纤维素是地球上最丰富的、可以再生的天然资源 ,具有价廉、可降解并对环境不产生污染等特点 ,因此世界各国都十分重视对纤维素的研究与开发。改性纤维素类吸附剂是目前纤维素功能高分子材料的重要发展方向之一。本文主要利用现有的文献资料从纤维素的溶解、纤维素珠体的研制以及球形再生纤维素的功能化等三个方面综合阐述了球形纤维素吸附剂的研究现状 。

As one of the most abundant renewable natural polymers on earth,cellulose has such advantages as low cost,degradability and non-pollution etc.These advantages have arisen increasingly interests of many researchers worldwide and thus served as the primary incentives for developing the cellulosic materials.Modified cellulose adsorbent is one of the major development tendencies of the cellulosic functional polymer materials.In this review,an extensive list of the spherical cellulose adsorbent literature has been compiled to provide a summary of available information on the cellulose solution,preparation of spherical cellulose beads and functionalization of the spherical cellulose adsorbents. The research actuality and development trend are also discussed here.
