In this study, hair waste was converted into active carbon for the first time and its characteristics were analyzed. As chemical activation tool, zinc chloride (ZnCl₂) was impregnated and then carbonized under different temperatures (250–300 °C). Scanning Electron Microscope (SEM) images showed an increase in the pore density, radius and volume of pores. X-ray diffraction analysis (XRD) showed that the samples had an amorphous structure. In Fourier-transform infrared (FT-IR) spectroscope analysis, C=C and N–H vibrations observed in 1515–1520 cm⁻¹ wave number of protein molecules were found to disappear with the increase in temperature. With Raman spectroscopy, the behaviors of D peak at 1344 cm⁻¹ wave number and G peak at 1566 cm⁻¹ wave number expressing structure layout in carbonized structures were analyzed depending on the temperatures. Between these intensities, (I_D/I_G) the rate was found to differ in direct proportion to temperature. XRD spectrums showed that the samples are converted into a more irregular crystal structure. All these results implied that the waste hair mass could be used as an adsorbant material.

使用化学活化法从废人头发中产生的活性炭的合成与表征

在这项研究中，头发废料首次被转化为活性炭，并对其特性进行了分析。作为化学活化工具，氯化锌（ZnCl ₂）浸渍后在不同温度（250–300°C）下碳化。扫描电子显微镜（SEM）图像显示孔密度，孔半径和体积增加。X射线衍射分析（XRD）表明样品具有非晶态结构。在傅立叶变换红外（FT-IR）光谱分析中，发现1515–1520 cm ^-1处蛋白质分子的波数随温度升高而消失，C = C和N–H振动消失。用拉曼光谱法，在1344 cm ^-1波数处的D峰和在1566 cm ^-1处的G峰的行为根据温度对碳化结构中的波数表示结构布局进行了分析。在这些强度之间（I _D / I _G），发现速率与温度成正比。XRD光谱表明样品被转化为更不规则的晶体结构。所有这些结果暗示废毛团可以用作吸附剂材料。
