油茶果壳对Al~(3+)和Ca~(2+)的吸附性能研究
|
摘要
探讨油茶果壳对Al~(3+)和Ca~(2+)的吸附性能,为果壳的资源化利用及林地施肥提供理论依据。利用果壳吸附溶液中的Al~(3+)和Ca~(2+),通过红外光谱分析和模型拟合,对其吸附特性进行了初步探讨。结果表明:1)果壳结构中含有大量的羧基和羟基等官能团,这些官能团能够提供与Al~(3+)和Ca~(2+)进行离子交换的H+;2)果壳对Al~(3+)和Ca~(2+)的吸附符合Freundlich模型,对Al~(3+)和Ca~(2+)的理论最大吸附量分别为11.39、11.04 mg/g;3)吸附过程符合准二级动力学模型,对Al~(3+)和Ca~(2+)的吸附过程主要受化学作用的控制,膜扩散和颗粒内扩散共同决定果壳吸附Al~(3+)和Ca~(2+)的速率;4)Al~(3+)和Ca~(2+)共存情况下,果壳对Al~(3+)的吸附高于Ca~(2+),且果壳对混合溶液中Al~(3+)和Ca~(2+)的吸附比单一溶液中的减少,二者之间存在竞争;5)油茶果壳是一种对Al~(3+)和Ca~(2+)有较好吸附性能的廉价吸附材料。
In order to promote Camellia oleifera fruit shell utilization, the metal ions adsorption ability of the shells was investigated.By using the shells to adsorb Al~(3+) and Ca~(2+) in solution, through methods of infrared spectrum analysis and model fitting, the adsorption characteristics of C. oleifera fruit shell were discussed. The results show that 1) In the shell structure there are a large number of carboxyl and hydroxyl groups, which can provide H+ for ion exchange with Al~(3+) and Ca~(2+); 2) The adsorption of the shells to Al~(3+) and Ca~(2+) accorded with Freundlich model, and the theoretical maximum adsorption capacity of Al~(3+) and Ca~(2+) were 11.39 and 11.04 mg/g, respectively; 3)The adsorption process conformed to the quasi two level kinetic model, the adsorption process of Al~(3+) and Ca~(2+) was mainly controlled by the chemical action, and the membrane diffusion and particle internal diffusion together determined the rate of Al~(3+) and Ca~(2+) adsorbed by the shell; 4) Under the coexistence of Al~(3+) and Ca~(2+), the adsorption of the shell to Al~(3+) was higher than to Ca~(2+), and the adsorption of Al~(3+)and Ca~(2+) in the mixed solution was less than that of single solution, and there was a competition between Al~(3+) and Ca~(2+); 5) The shell of C.oleifera is a cheap adsorptive material which has good properties for adsorbing Al~(3+) and Ca~(2+).
