Herein, an economical sugar-based carbon synthesized in the previous study was modified using lanthanum and cobalt bimetal species by a simple method for the first time. The obtained adsorbent named La/Co-SC was analyzed using some classical characterization techniques. Results obtained indicate that the specific surface area and pore volume of the La/Co-SC are higher than the original sugar-based carbon (SC). Additionally, the La/Co-SC exhibits an excellent adsorption performance with methyl orange (MO), which is about 2.5 times better than the original SC. Further investigations reveal that the adsorption process is endothermic and it obeyed the pseudo-second order kinetic model and Langmuir isotherm model. Moreover, the La/Co-SC shows a good regeneration ability, indicating its great potential as an economical and environmental-friendly adsorbent.

在此，首次使用镧和钴双金属物种通过简单的方法对先前研究中合成的经济型糖基碳进行了改性。使用一些经典表征技术分析获得的名为 La/Co-SC 的吸附剂。获得的结果表明，La/Co-SC 的比表面积和孔体积高于原始糖基碳 (SC)。此外，La/Co-SC 对甲基橙（MO）表现出优异的吸附性能，比原来的 SC 好约 2.5 倍。进一步的研究表明，吸附过程是吸热的，并且遵循准二级动力学模型和朗缪尔等温线模型。此外，La/Co-SC 显示出良好的再生能力，
