摘要
本研究制备了一种新的廉价环保的茄子茎基生物吸附剂，用于去除溶液中的Cu2+、Ni2+和Co2+重金属离子。测定了玉米淀粉和油脂含量对玉米密度、重金属萃取性能、进水量和溶解度等物理性质的影响。火焰原子吸收光谱法(FAAS)已用于测定生物吸附剂的萃取性能。根据ASTM D 792标准测定了生物吸附剂的密度。结果表明，未经处理的茄子茎基生物吸附剂吸附Co2+离子5.36 mg, Ni2+离子4.99 mg。在室温下，175 rpm搅拌速度下，从25 ml 7 ppm的重金属离子溶液中提取4.84 mg的Cu2+离子。
Aubergine-based Biosorbents for Heavy Metal Extraction
In this research, a new alternative inexpensive and eco-friendly Aubergine (Eggplant) stems-based biosorbents having produced to remove Cu2+, Ni2+, and Co2+ heavy metal ions from the solution. Moreover, how the corn starch and oil contents affect physical properties like density, heavy metal extraction performance, water intake, and solubility had been determined. Flame atomic absorption spectroscopy (FAAS) having used the determination of biosorbents extraction performance. The density of the biosorbents had determined according to ASTM D 792 standards. As a result, the untreated eggplant stalk-based biosorbent adsorbed 5.36 mg Co2+ ions, and 4.99 mg of Ni2+ ions. Also, 4.84 mg of Cu2+ ions were extracted from 25 ml 7 ppm of heavy metal ions solutions for 30 minutes, at room temperature with 175 rpm agitation speed by Eggplant-based biosorbents.
