This study focuses on preparation of new adsorbent for copper by radiation induced grafting (RIG) of 2,3-epoxypropyl methacrylate (EMPA) onto PP/PE non-woven fabric (NWF) with subsequent functionalization with phosphoric acid (PA). The density of phosphoric acid incorporated onto EMPA-g-NWF was tuned by reaction parameters optimization such as PA concentration, reaction temperature, reaction time and EMPA grafting yield by using response surface method (RSM) engaging Box-Behnken design (BBD). Maximum PA density of 2.0 mmol/g⁻¹ was estimated at optimum reaction parameter of 45.50% PA concentration, 70 °C reaction temperature, 2.76 h reaction time and 132.68% grafting yield. The deviation between optimum experimental and projected phosphoric acid density was taken into consideration, in order to verify the consistency of RSM in predicting the yield and optimizing the functionalization reaction parameters. The PA-functionalized EMPA-g-NWF was assessed with X-ray diffraction (XRD), Fourier-transform infrared (FT-IR) spectroscopy, thermogravimetric (TGA), X-ray photoelectron spectroscopy (XPS), and scanning electron microscopy-energy dispersive x-ray (SEM-EDX) to examine the crystallinity, chemical composition, thermal stability and morphology, and respectively. The preliminary study on adsorption of copper was carried out with PA-functionalized EMPA-g-NWF at different conditions such as different initial copper concentration, PA density and contact time. The maximum adsorption was obtained at pH of 4. The adsorption capacity increases as the PA density increases and maximum adsorption obtained at 2.5 mmol/g^-ad of PA density. The adsorption results obtained was very promising and suggested PA-functionalized EMPA-g-NWF as a suitable candidate for copper removal.

这项研究的重点是通过将辐射引发的甲基丙烯酸2,3-环氧丙酯（EMPA）接枝到PP / PE无纺布（NWF）上，然后用磷酸（PA）进行官能化来制备新的铜吸附剂。通过采用Box-Behnken设计（BBD）的响应面法（RSM）通过反应参数优化（例如PA浓度，反应温度，反应时间和EMPA接枝产率）优化了掺入EMPA-g-NWF的磷酸的密度。最大PA密度为2.0 mmol / g ^-1在45.50％PA浓度，70°C反应温度，2.76 h反应时间和132.68％接枝收率的最佳反应参数下估算得到的收率。为了验证RSM在预测收率和优化官能化反应参数方面的一致性，考虑了最佳实验磷酸密度与预计磷酸密度之间的偏差。通过X射线衍射（XRD），傅立叶变换红外（FT-IR）光谱，热重（TGA），X射线光电子能谱（XPS）和扫描电子显微镜对PA功能化的EMPA-g-NWF进行了评估-能量色散X射线（SEM-EDX）分别检查结晶度，化学成分，热稳定性和形态。在不同的条件下，例如不同的初始铜浓度，PA密度和接触时间，用PA-官能化的EMPA-g-NWF进行了对铜的吸附的初步研究。在pH值为4时获得最大吸附。随着PA密度的增加，吸附容量增加，在2.5 mmol / g时获得最大吸附。^-PA密度广告。获得的吸附结果非常有前途，并建议使用PA-官能化的EMPA-g-NWF作为去除铜的合适候选物。
