Abstract

Biographene was prepared through the pyrolysis of Acacia nilotica waste using diverse temperatures and time spans. The obtained materials were characterized using scanning electron microscope (SEM), transmission electron microscopy (TEM), energy-dispersive X-ray spectrometry (EDX), X-ray diffraction analysis (XRD), and Fourier transform infrared spectroscopy (FTIR) methods. The data obtained indicated that when the temperature and time increased, the texture of the biographene became more porous with greater carbon content. The effect of various variables on Cd(II) adsorption, using the optimized biographene product, was investigated, and the results revealed that the optimum pH was 4 and the maximum adsorption capacity was 118.9 mg/g. The Langmuir isotherm model and pseudo-second-order kinetic model best fit the equilibrium data, indicating the adsorptive behavior of the as-prepared biographene implying a homogenous monolayer surface. The recyclability investigation elucidates the remarkable potentiality of up to five consecutive cycles. As such, the biographene-based Acacia nilotica could be considered a sustainable candidate for cadmium removal from polluted water.

利用优化的金合欢生物皂去除合成水和实际污染水中的 Cd2+
利用不同的温度和时间跨度热解金合欢废料,制备出生物烯。使用扫描电子显微镜(SEM)、透射电子显微镜(TEM)、能量色散 X 射线光谱法(EDX)、X 射线衍射分析法(XRD)和傅立叶变换红外光谱法(FTIR)对获得的材料进行了表征。所得数据表明,当温度和时间增加时,生物拉芬的质地变得更加多孔,含碳量更高。使用优化的生物合成烯产品,研究了各种变量对 Cd(II) 吸附的影响,结果表明最佳 pH 值为 4,最大吸附容量为 118.9 mg/g。朗缪尔等温线模型和伪二阶动力学模型最适合平衡数据,表明制备的生物合成烯具有吸附行为,意味着其表面为均匀的单层。可循环性研究阐明了生物拉芬可连续循环五次的显著潜力。因此,基于生物皂苷的金合欢可被视为一种可持续的候选材料,用于去除污染水体中的镉。
