A comparison study of an electrolytic, adsorption, and a novel hybrid method towards the removal of malachite green (MGD) dye from the aquatic environment utilizing agricultural biomass, Eucalyptus globulus seeds was examined. The synthesized material has been characterized by thermogravimetric analysis, SEM, FTIR, and XRD. The acid-modified biosorbent developed a microporous structure suggesting a suitable removal process of MDG. The hybrid method was carried in an indigenously designed three-phase three-dimensional electrolytic reactor with varying applied voltage (6, 9, and 12 V) with biosorbent serving as particle electrode. The hybrid method gave the highest removal rate at a voltage of 12 V, compared to other methods. Moreover, the dye removal capacity increased with increased voltage, and contact time was optimized at 15 min. The adsorption isotherm was well fitted with Freundlich isotherm and kinetic data represented pseudo-second-order. Intra particle diffusion studies suggested no interference with gradual adsorption from macropores to micropores. The removal efficiency of particles electrodes for 6, 9, and 12 V were 95, 97, and 99.8%, respectively. The higher removal of MDG towards the hybrid system may be assigned to the synergistic effect of electrolytic and adsorption systems. Regeneration studies indicated that the biosorbent can be reused up to ten times without appreciable loss of efficiency.

电解，吸附和新型混合方法利用农业生物质桉树从水生环境中去除孔雀石绿（MGD）染料的比较研究检查种子。合成材料已通过热重分析，SEM，FTIR和XRD进行了表征。酸改性的生物吸附剂形成了微孔结构，表明有合适的MDG去除工艺。混合法在本地设计的三相三维电解反应器中进行，该反应器具有不同的施加电压（6、9和12 V），生物吸附剂用作颗粒电极。与其他方法相比，混合方法在12 V的电压下具有最高的去除率。此外，染料去除能力随电压的增加而增加，并且接触时间在15分钟时达到最佳。吸附等温线与Freundlich等温线非常吻合，动力学数据表示伪二级。颗粒内扩散研究表明，从大孔到微孔的逐渐吸附不会产生干扰。对于6、9和12 V，颗粒电极的去除效率分别为95％，97％和99.8％。MDG向混合系统的较高去除率可归因于电解和吸附系统的协同效应。再生研究表明，该生物吸附剂可以重复使用多达十次，而不会明显降低效率。
