摘要
磁性高分子微球的研究始于70年代,同时因具有磁性,已广泛应用于在医学、生物工程、环境工程、分析化学等众多领域。而以海带为原料制备的磁性高分子微球,价廉易得、吸附量大,具有巨大的应用潜力,已成为复合磁性功能材料的一个新研究热点。
本文以海带为原材料,以纯海藻酸钠为参比,采用包埋法,制备海藻酸钠磁性纳米颗粒,然后研究了其对钼吸附的吸附机理、吸附动力学等,取得了令人满意的结果。实验得出:
1) 在pH=1的酸度条件下,两种原料制备的吸附剂对Mo(VI)的吸附表现出了良好的吸附性能。
2) 吸附剂对Mo(VI)的吸附速率较快,可以在较短的一段时间达到平衡。吸附过程可以用拟一级反应速率方程来拟合。
3)制备的吸附剂及其参比的吸附剂对Mo(VI)的吸附量分别为112.00mg-Mo(VI)/ g和115.00mg-Mo(VI)/ g。
由上述内容可得,以海带为原料制备的生物质吸附剂,是一种天然的优质的高效吸附剂,在提倡环保和节约型社会的今天,其在金属的分离、去除和回收方面显示了应用前景。
不好意思,拉了一句话

Magnetic polymer microsphere research began in the 70 s, at the same time because has magnetic, has been widely used in medical and biological in engineering, environmental engineering, analytical chemistry, etc. And for the preparation of raw materials to explore magnetic polymer microspheres, cheap, adsorption capacity, has great potential applications, has become a complex magnetic functional materials a new hotspot.
This paper attempts to explore as raw material, aluminum sodium alginate than as reference, the embedding method, preparation sodium alginate magnetic nanoparticles, then the adsorption of molybdenum of adsorption mechanism, adsorption dynamics and so on, have achieved satisfactory results. Experiment:
1) in pH = 1 acidity condition, two kinds of raw materials to the preparation of adsorbents to Mo (VI) adsorption showed good adsorption performance.
2) adsorbents to Mo (VI) adsorption rate faster, can be in relatively short period of time to achieve the balance. Adsorption process can be used to level the reaction rate equation to fitting.
3) the preparation and the absorbent CST adsorbents to Mo (VI) the adsorption quantity of were 112.00 mg-Mo (VI) / g and 115.00 mg-Mo (VI) / g.
From the above content, to explore the preparation of raw materials for biomass adsorbent, is a natural high-quality efficient absorbent, environmental protection and economical society in advocating the today, in the separation of the metal, remove and recovery that show the application prospect.
Magnetic polymer microsphere research began in the 70 s. It is divided polymer of particles properties, through the copolymerization and surface modification methods of reaction to the surface of sexual function groups (OH,-COOH, CHO,-- NH2,,-SH, etc), and, at the same time, because of its magnetic, has been widely used in medical and biological in engineering, environmental engineering, analytical chemistry, etc.

Research on magnetic polymer microsphere began in the 70's, at the same time because of having magnetic properties, has been widely used in medicine, biological engineering, environmental engineering, analytical chemistry and other fields. But to seaweed as raw materials for the preparation of magnetic polymer microspheres, cheap, large adsorption capacity, and has huge application potential of composite magnetic functional materials, has become a new research hotspot.
This article to seaweed as raw materials, pure sodium alginate as the reference, using the embedding method, preparation of alginate magnetic nanoparticles, then studied its effects on molybdenum adsorption, adsorption kinetics, adsorption mechanism, achieved satisfactory results. Experiments:
1) at pH = 1acidity condition, two kinds of raw materials for the preparation of adsorbents for the adsorption of Mo ( VI ) showed good adsorption properties.
2) adsorbent to Mo ( VI ) adsorption rate is rapid, can be in a relatively short period of time to reach equilibrium. The adsorption process can use the pseudo-first order reaction equation.
3) preparation of the adsorbent and its reference of the adsorbent to Mo ( VI ) adsorption capacity were 112.00mg-Mo ( VI ) / g and 115.00mg-Mo / g ( VI ).
The content available to seaweed as raw materials, preparation of biomass adsorbent, is a high-quality natural adsorbents, in promoting environmental protection and managing model of the society today, the metal separation, removal and recovery of hand shows the application prospect.
