Abstract

Various industrial, agricultural, household, mining, smelting, and chemical industrial activities can generate waste containing heavy metals such as Fe(III). Fly ash has the potential as an effective adsorbent to capture heavy metals in wastewater. This study aims to immobilize coal fly ash in alginate beads for the adsorption of Fe(III) ions from synthetic waste solution. To test the adsorption capability of fly ash-alginate beads was performed by varying the contact time (1-24 hours), the mass of fly ash-alginate beads (5, 15, 35, 45, and 55 grams), and the initial concentration of Fe (III) ions at 6, 8, and 10 ppm. The determination of the concentration after adsorption was done using a UV-Vis spectrophotometer. The results showed that fly ash-alginate beads were able to remove Fe(III) ions up to 68.60% at a bead mass of 55 g, ion concentration of 10 ppm, and the equilibrium contact time was reached after 5 hours. The analysis results indicated that the adsorption mechanism followed the Freundlich isotherm model due to the heterogeneous surface exhibited.

将煤粉灰固定在海藻酸珠中以吸附铁 (III) 离子

各种工业、农业、家庭、采矿、冶炼和化学工业活动都会产生含有重金属（如铁(III)）的废物。粉煤灰具有作为有效吸附剂捕捉废水中重金属的潜力。本研究旨在将粉煤灰固定在藻酸盐珠中，以吸附合成废液中的铁(III)离子。通过改变接触时间（1-24 小时）、粉煤灰-海藻酸盐珠的质量（5、15、35、45 和 55 克）以及铁（III）离子的初始浓度（6、8 和 10 ppm）来测试粉煤灰-海藻酸盐珠的吸附能力。使用紫外可见分光光度计测定吸附后的浓度。结果表明，当珠子质量为 55 克、离子浓度为 10 ppm、平衡接触时间为 5 小时时，粉煤灰-海藻酸珠对铁（III）离子的去除率高达 68.60%。分析结果表明，由于表面呈现异质性，吸附机理遵循 Freundlich 等温线模型。
