Abstract

A lot of wastes are generated in the wood industries which constitute series of negative environmental effects. Nevertheless, sawdust has some organic compounds which can remove heavy metal ions from an aqueous solutions using the adsorption procedure. This investigated the potentials of three hardwood species for the removal of cadmium ion from contaminated water. The wood species utilized in this study include Triplochiton scleroxylon, Brachystegia eurycoma, and Blighia sapida sawdust. The sawdust samples were sieved before the pretreatment to remove both impurities and extractives. The experiments were conducted in batches for adsorption in order to determine the effect of pH solution, contact time, on adsorption of cadmium ions. The experiment was laid out in a 3 × 2 × 4 factorial experimental design. The results revealed that the adsorption capacity for (treated and untreated species, Triplochiton scleroxylon, Brachystegia eurycoma and Blighia sapida (treated and untreated) were 92.40±6.42% and 82.66±13.25%, 85.43±17.21%, and 78.00±24.15%, 78.00±20.08% and 80.75±17.07% respectively at the different pH levels (1-4). The results at the optimum pH (2) also revealed that the adsorption capacity for treated and untreated species of Triplochiton scleroxylon, Brachystegia eurycoma and Blighia sapida were 96.99±1.76% and 96.99±1.68%, 97.94±1.20% and 98.48±0.66%, 97.73±1.59% and 99.10±0.81% respectively at the different contact time (30, 60, 90 and 120). This research revealed that pre-treated sawdust adsorbed metal ions faster even at a low time interval compared to untreated samples. Also, it was observed that the highest adsorption capacity (%) of cadmium took place at pH 2 for all samples of sawdust both (treated and untreated). Hence, the selected wood species were found appropriate for the extraction of cadmium from contaminated water and therefore recommended for use.

三种硬木木屑作为低成本吸附剂去除水中镉的效果评价
木材工业产生了大量的废弃物,构成了一系列的负面环境影响。然而,木屑含有一些有机化合物,可以通过吸附程序从水溶液中去除重金属离子。研究了三种硬木对污染水中镉离子的去除率。本研究利用的木材种类有:硬皮龙(Triplochiton cleroxylon)、泛舟木屑(Brachystegia eurycoma)和白螺旋体木屑(Blighia sapida锯末)。预处理前对木屑样品进行筛分,去除杂质和萃取物。为了确定溶液的pH值、接触时间对镉离子吸附的影响,进行了批量吸附实验。试验采用3 × 2 × 4因子试验设计。结果表明:在不同pH水平下,经处理和未处理的钉螺、粗腹短腹虫和刺头Blighia(处理和未处理)的吸附量分别为92.40±6.42%和82.66±13.25%、85.43±17.21%和78.00±24.15%、78.00±20.08%和80.75±17.07%。在最适pH(2)条件下,不同接触时间(30、60、90和120)下,处理过的和未处理过的钉螺、粗腹棘虾和刺腹Blighia sapida的吸附量分别为96.99±1.76%和96.99±1.68%、97.94±1.20%和98.48±0.66%、97.73±1.59%和99.10±0.81%。该研究表明,与未处理的样品相比,预处理木屑即使在较低的时间间隔内也能更快地吸附金属离子。此外,观察到在pH为2时,所有样品(处理和未处理)对镉的吸附量最高(%)。因此,所选择的木材品种适合从污染水中提取镉,因此推荐使用。
