这项研究提出了一种创新的双壁硼硅酸盐玻璃反应器系统,用于有效处理液态和气态废水。该反应器系统允许精确的温度控制,连续pH监测,和控制试剂的剂量以优化反应条件。通过X射线衍射(XRD)进行了详细的表征,傅里叶变换红外光谱(FTIR),BET(比表面积)分析,零电荷点(PZC),和SCR的扫描电子显微镜(SEM),SCRT,和5%Fe@SCRT材料。对于孔雀石绿吸附,使用Langmuir等温模型,SRCT显示的最大吸附容量为39.78±0.5mg/g,并遵循伪二级动力学。发现吸附的最佳条件是:初始浓度为50ppm,吸附剂用量为1克/升,pH值为8.5,温度为50°C。对于苯酚的催化氧化,5%Fe@SRCT在最佳条件下(50ppm苯酚,1g/l催化剂用量,pH3.5,H2O2浓度8.7mM,和温度70°C)。反应过程中鉴定的中间体包括氢醌,苯醌,儿茶酚,和间苯二酚,降解发生在60分钟的反应期间。5%Fe@SCRT材料在催化氧化去除苯酚方面表现出优异的可重用性,在三个周期内没有明显的效率损失,同时,SRCT经历了三个再生循环,以吸附孔雀石绿。清除剂测试证实了羟基自由基参与催化氧化过程。此外,5%Fe@SRCT催化氧化苯酚后的鱼存活试验表明,对鱼没有影响,强调这一过程的环境安全。此外,通过SRCT对MG进行脱色后的发芽试验显示出良好的效果,没有负面影响,加强这项创新技术的生态价值。这些结果突出了SCRT和5%Fe@SCRT作为环境修复的多功能材料的创新用途。在拟议的双壁硼硅酸盐玻璃反应器系统中利用其有效的吸附能力和有效的催化氧化性能。实践要点:该研究证明了采用SRCT吸附剂和Fe@SRCT催化剂的创新反应器系统有效去除废水中的孔雀石绿和苯酚。环境影响评估,包括种子萌发和鱼类生存评估,验证该方法的生态友好潜力。实施这种方法可以大大有助于可持续的水处理实践。
This study presents an innovative double-walled borosilicate glass
reactor system for the efficient treatment of liquid and gaseous wastewater. This
reactor system allows precise temperature control, continuous pH monitoring, and controlled dosing of reagents to optimize reaction conditions. Detailed characterization was carried out by X-ray diffraction (XRD), Fourier transforms infrared spectroscopy (FTIR), BET (specific surface area) analysis, point of zero charge (PZC), and scanning electron microscopy (SEM) for the SCR, SCRT, and 5%Fe@SCRT materials. For Malachite Green adsorption, SRCT demonstrated a maximum adsorption capacity of 39.78 ± 0.5 mg/g using the Langmuir isotherm model and followed pseudo-second-order kinetics. Optimum conditions for adsorption were found to be: an initial concentration of 50 ppm, an adsorbent dosage of 1 g/l, a pH of 8.5, and a temperature of 50°C. For the catalytic oxidation of phenol, 5%Fe@SRCT achieved a remarkable removal rate of 99.9 ± 0.1% under optimum conditions (50 ppm phenol, 1 g/l catalyst dosage, pH 3.5, H2O2 concentration 8.7 mM, and temperature 70°C). Intermediates identified during the reaction included hydroquinone, benzoquinone, catechol, and resorcinol, with degradation occurring over a 60-minute reaction period. The 5%Fe@SCRT material showed excellent reusability in the removal of phenol by catalytic oxidation, with no significant loss of efficiency over three cycles, while the SRCT underwent three cycles of regeneration for the adsorption of Malachite Green. Scavenger tests confirmed the involvement of hydroxyl radicals in the catalytic oxidation process. In addition, fish survival tests after catalytic oxidation of phenol by 5%Fe@SRCT showed no impact on fish, underlining the environmental safety of this process. In addition, germination tests after decolorization of MG by SRCT demonstrated a good effect with no negative impact, reinforcing the ecological value of this innovative technology. These results highlight the innovative use of SCRT and 5%Fe@SCRT as versatile materials for environmental remediation, exploiting their effective adsorption capacities and efficient catalytic oxidation performance within the proposed double-walled borosilicate glass
reactor system. PRACTITIONER POINTS: The study demonstrates the effectiveness of an innovative
reactor system employing SRCT adsorbent and Fe@SRCT catalyst for efficient removal of malachite green and phenol from wastewater. Environmental impact assessment, including seed germination and fish survival evaluation, validates the method\'s eco-friendly potential. Implementation of this approach could significantly contribute to sustainable water treatment practices.
