Nickel (Ni) leftovers arise from both catalyst application interventions and Ni alloy piping of the cooking oil industry (COI) being wasted as pollutants of freshwater bodies via discharged effluent. The current study assessed one of the indigenously feasible Ni removal systems comprising autochthonous Gomont (AP)-driven Ni phycoremediation cells (NPCs). After screening AP for hyperaccumulation in the Ni spiked solution, AP was transferred to the NPCs. Propagation of the AP inoculum was proportionate to the pollution load drop of COI with 22.97 and 55.07% drops in the biochemical (BOD) and chemical oxygen demand (COD), respectively. With the 0.11 bioconcentration factor, there was an uptake of 14.24 g mineral with 16.22% Ni removal and a 36.35 desorption ratio. The experimental data closely fitted with the Langmuir and Freundlich isotherms, respectively. The study concluded that could be taken for treatment of Ni-loaded industrial effluents at the microcosmic level.
镍 (Ni) 残留物既来自催化剂的应用干预，也来自烹饪油行业 (COI) 的镍合金管道，它们作为污染物通过排放的废水进入淡水体。本研究评估了一种本土可行的镍去除系统，该系统包括土著的戈蒙特 (AP) 驱动的镍植物修复细胞 (NPC)。在筛选出对 Ni 污染溶液具有超积累能力的 AP 后，将 AP 转移到 NPC 中。随着 COI 污染负荷的下降，AP 接种物的繁殖与生化需氧量 (BOD) 和化学需氧量 (COD) 的下降成比例，分别下降了 22.97%和 55.07%。生物浓缩因子为 0.11，矿物的吸收量为 14.24 克，Ni 的去除率为 16.22%，解吸率为 36.35%。实验数据分别与 Langmuir 和 Freundlich 等温线拟合良好。研究得出结论，AP 可以在微观水平上用于处理含 Ni 的工业废水。
