摘要

以6-氨基己酸为官能团，采用波拉斯法合成了罗望子天然多糖基树脂。通过批处理法和柱分离实验对原液和工业废水中有毒金属离子的吸附率进行了评价。研究了它们的体积密度、离子交换容量和红外光谱等理化性质。采用间歇平衡法，研究了5种金属离子在不同pH水平下的Kd值。TACA树脂对Cu+2、Fe+2、Zn+2、Cd+2和Pb+2的最大去除率分别为97.97%、97.80%、96.39%、94.94%和91.90%。pH = 2 ~ 8时，这些离子的分布比为Cu+2 >铁+ 2比;锌+ 2比;Cd + 2比;Pb + 2。利用离子交换树脂去除冶金和矿产工业排放样品中的有毒金属离子。Zn(Ⅱ)、Pb(Ⅱ)、Cd(Ⅱ)、Cu(Ⅱ)和Fe(Ⅱ)的回收率分别为95.44、96.27、96.41、98.82和100%。TACA树脂的离子交换容量为2.24mmol/g

Synthesis and Characterization of 6-Amino Caproic Acid Tkp-Based Resin for Wastewater Treatment

The natural polysaccharide-based resin of tamarind using functional group as 6-amino caproic acid has been synthesized by porath’s method. Their adsorption behavior also evaluated by determination of % adsorption of toxic metal ions from stock solution as well as industrial effluents by batch method and column separation experiment. Their physiochemical properties as bulk density, ion exchange capacity, and FTIR, were investigated. Using the batch equilibrium approach, Kd of five metal ions at various pH levels was investigated. The maximum removal % of metal ions of Cu+2, Fe+2, Zn+2, Cd+2, and Pb+2 at TACA resin were found at 97.97%,97.80%, 96.39%, 94.94%, and 91.90% respectively. Distribution ratio of these ions observed from pH 2 to 8 was Cu+2 > Fe+2> Zn+2> Cd+2 > Pb+2. The toxic metal ions from discharge samples of the metallurgical and mineral industries have been removed using ion exchange resins. Recovery of Zn (Ⅱ), Pb (Ⅱ), Cd (Ⅱ), Cu (Ⅱ), and Fe (Ⅱ) were obtained at 95.44, 96.27, 96.41, 98.82, and 100% respectively. The ion exchange capacity of TACA resin was found 2.24mmol/g
