In this investigation, the efficiency of Codium vermilara for copper ions removal from aqueous solution was studied. Central Composite Design has been used for the Response Surface Methodology and has been found to be an effective method for investigating the influences of various variables and their interactions on the efficiency of Cu²⁺ ions removal. The interactive impacts of four variables: algal dose, pH, initial concentrations of copper and contact time on the copper removal efficiency were assessed. Algal dose 0.75 g/L, pH 5.28, contact time 70.51 min, and copper concentration 48.75 mg/L were found to be the conditions of optimum biosorption. The efficiency of copper removal was found to be 85.5% under these optimum conditions. Copper removal on the biomass of C. vermilara followed well the kinetics of pseudo-first-order, Elvoish and Intraparticle diffusion. Compared to the other models, Dubinin-Radushkevich isotherm best suited the experimental data revealing that the adsorption mechanism was physical adsorption. Thermodynamic parameters exhibited non-spontaneous, randomness and endothermic biosorption of Cu²⁺ ions. Additionally, the biosorbent characterization was estimated by scanning electron microscopy and Fourier transform infrared analysis. Thus, C. vermilara could be used as possible biosorbent for removing heavy metals and other pollutants from the environment.

在这项研究中，研究了银朱精从水溶液中去除铜离子的效率。中央复合设计已被用于响应表面方法，已被发现是研究各种变量及其相互作用对Cu ²⁺离子去除效率的影响的有效方法。评估了四个变量的交互影响：藻类剂量，pH，铜的初始浓度和接触时间对铜去除效率的影响。发现藻类剂量为0.75 g / L，pH 5.28，接触时间为70.51分钟和铜浓度为48.75 mg / L是最佳生物吸附的条件。在这些最佳条件下，发现铜的去除率为85.5％。去除铜对生物质的影响C. vermilara很好地遵循了拟一阶，Elvoish和粒子内扩散的动力学。与其他模型相比，Dubinin-Radushkevich等温线最适合实验数据，表明吸附机理是物理吸附。热力学参数表现出Cu ²⁺离子的非自发，无规和吸热生物吸附。另外，通过扫描电子显微镜和傅立叶变换红外分析来估计生物吸附剂的表征。因此，C。vermilara可用作可能的生物吸附剂，用于从环境中去除重金属和其他污染物。
