In this investigation, the hybrid of ZrO₂ decorated rGO functionalised carbon foam (ZRCF) as template has been introduced for removing arsenic (V) (As(V)) contamination from the water and easily separated out from water after post decontamination without any separation techniques. An excellent arsenic (As(V)) removal efficiency of 45.4μgg⁻¹ in 60 min has been revealed by prepared ZRCF treated at 300 °C in air. Further probing the adsorption mechanism, both linear and nonlinear kinetics and isotherm models have been employed on the experimental data. It is revealed that the fitted linear kinetics data better explains the PSO kinetics and linear adsorption isotherm describes the best fitting of equilibrium data in Langmuir isotherm based on the regression coefficient (0.98) and χ2 (7.40) value. The present investigation is evaluated the adsorption mechanism between adsorbate and adsorbent such as electrostatic attraction, HSAB reaction and bi-dentate ligand formation.

在这项研究中，引入了ZrO ₂装饰的rGO功能化碳泡沫（ZRCF）作为模板的杂合物，用于从水中去除砷（V）（As（V））污染，并且在去污后很容易从水中分离出来而没有任何分离技术。极佳的砷（As（V））去除效率为45.4μgg ^-1制备的ZRCF在300°C的空气中处理后，在60分钟内就显示出。为了进一步探究吸附机理，实验数据采用了线性和非线性动力学以及等温线模型。结果表明，拟合的线性动力学数据更好地解释了PSO动力学，线性吸附等温线基于回归系数（0.98）和χ2（7.40）值描述了Langmuir等温线中平衡数据的最佳拟合。本研究评估了吸附物和吸附剂之间的吸附机理，例如静电吸引，HSAB反应和双齿配体形成。
