摘要

为了有效去除水中的重金属离子,人们对曝气、混凝、过滤、沉淀和吸附等各种方法进行了深入研究。吸附法,特别是以花生壳粉末作为生物吸附剂的柱吸附法,是一种实用、有效和高效的方法。在这项研究中,使用的固定变量为 50 克吸附剂、粒度为 35 目、初始吸附剂浓度为 100 ppm、吸附剂容量为 10 升、流速为每分钟 4 升。取样间隔为 0、15、30、45、60、75、90、105、120、135 和 150 分钟,自变量包括未处理吸附剂、物理活化吸附剂以及使用 1N H2SO4 和 1N NaOH 的化学活化吸附剂。结果表明,Fe2+ 的吸附明显受到活化剂类型的影响。在 135 分钟时,Fe2+ 的去除率最高,达到 55.90%,显示了生物吸附过程的有效性。值得注意的是,使用 1N NaOH 可以达到最佳的生物吸附剂活化效果。这项研究为重金属离子的动态去除提供了宝贵的见解,强调了花生壳粉末生物吸附的重要性,并突出了特定活化方法对吸附过程效率的影响。

ENHANCING BIOADSORPTION EFFICIENCY OF PEANUT SKIN BASED ON PHYSICAL AND CHEMICAL ACTIVATION METHODS IN FE2+ ION REMOVAL USING COLUMN TECHNIQUE IN ARTIFICIAL WASTEWATER
In the interest of efficient heavy metal ion removal from water, various methods such as aeration, coagulation, filtration, sedimentation, and adsorption have been thoroughly investigated. Adsorption, specifically the column method with groundnut shell powder as a bio adsorbent, stands out as a practical, effective, and efficient approach. In this study, a fixed variable of 50 g adsorbent, a particle size of 35 mesh, and an initial adsorbate concentration of 100 ppm was used, along with a 10-liter adsorbate volume and a flow rate of 4 liters per minute. Sampling intervals of 0, 15, 30, 45, 60, 75, 90, 105, 120, 135, and 150 minutes were chosen, and the independent variables encompassed untreated adsorbents, physically activated adsorbents, and chemically activated adsorbents using 1N H2SO4 and 1N NaOH. The outcomes revealed that the adsorption of Fe2+ was notably influenced by the type of activator. The highest Fe2+ removal percentage, 55.90%, was achieved at 135 minutes, showcasing the efficacy of the bioadsorption process. Notably, the optimal bioadsorbent activation was attained using 1N NaOH. This study provides valuable insights into the dynamics of heavy metal ion removal, emphasizing the significance of bioadsorption with groundnut shell powder and underscoring the impact of specific activation methods on the efficiency of the adsorption process.
