摘要

研究了玉米丝活性炭（CS-AC）和玉米丝水焦活性炭（CS-HC-AC）的开发和优化，作为一种可持续的水净化解决方案。首次采用水热活化法制备了结构性能较好的玉米丝AC。CS-HC-AC的SBET表面积为331.233 m2 g−1，超过了CS-AC的7.335 m2 g−1。对温度、活化时间、活化率等关键因素（活化率100%、活化温度500℃、活化时间60 min）进行了优化，K2CO3和ZnCl2分别为CS-AC和CS-HC-AC最有效的活化剂。活性炭对重金属（Cr（VI）、Pb（II）、Ni(II)）和亚甲基蓝染料具有较高的吸附能力。

Optimized Synthesis and Characterization of Activated Carbon from Corn Silk and Corn Silk Hydrochar

This study investigates the development and optimization of activated carbon (AC) from corn silk (CS-AC) and corn silk hydrochar (CS-HC-AC) as a sustainable solution for water purification. For the first time, hydrothermal treatment and activation processes were employed, producing AC from corn silk with improved structural properties. CS-HC-AC exhibited a remarkable S_BET surface area of 331.233 m² g⁻¹, surpassing the 7.335 m² g⁻¹ of CS-AC. Key factors such as temperature, activation time, and activator rate were optimized (100% activator rate, 500 °C temperature, and 60 min activation time), with K₂CO₃ and ZnCl₂ identified as the most effective activators for CS-AC and CS-HC-AC, respectively. The resulting ACs showed high adsorption capacities for heavy metals (Cr(VI), Pb(II), and Ni(II)) and methylene blue dye.
