    Herein, blended rubber seed pericarp (RSP) and sunflower seed pericarp (SFSP) were converted into mesoporous activated carbon adsorbent (RSPSFSP-AC) to remove a toxic cationic dye namely fuchsin basic (FB) dye from aqueous environment. The thermochemical conversion process was carried out by using microwave irradiation assisted ZnCl2 activation for 15 min with 800 W. The physicochemical properties of RSPSFSP-AC were evaluated using several analytical techn... ...点击完成人机验证后继续浏览

    在此研究中,将混合的橡胶籽果皮(RSP)和向日葵籽果皮(SFSP)转化为介孔活性炭吸附剂(RSPSFSP-AC),以从水环境中去除有毒阳离子染料——基性品红(FB)染料。热化学转化过程通过使用800瓦微波照射辅助ZnCl2活化15分钟完成。采用pHpzc、BET、FTIR和SEM-EDX分析等多种技术评估了RSPSFSP-AC的理化性质。利用Box-Behnken设计(BBD)和期望函数优化了RSPSFSP-AC对FB去除的吸附性能。最优条件下,RSPSFSP-AC在0.09 g/100 mL剂量下,在pH值为9.2时,FB去除率达到92.8%。FB染料的吸附动力学和等温线模型分别由伪二级(PSO)模型和Langmuir等温线模型解释。RSPSFSP-AC对FB染料的最大吸附容量(qmax)为147.7 mg/g。FB染料在RSPSFSP-AC表面的吸附可归因于多种可能的相互作用,包括π-π堆积、静电作用力、孔隙填充和氢键形成。因此,本研究结果表明,RSPSFSP-AC具有从水环境中捕获阳离子染料的应用潜力。

    简明摘要:

    该研究的创新之处在于,将橡胶(Hevea brasiliensis)和向日葵(Helianthus annuus)混合木质纤维素生物质废物转化为介孔活性炭,使用微波辅助ZnCl2热化学活化工艺。此外,制备出的活性炭成功应用于去除基性品红(FB)染料。
