摘要
以新疆薄皮核桃壳为原料,通过微波辅助活化技术,采用响应面法,进行了颗粒活性炭制备技术的优化,确定了微波法活化技术制备核桃壳活性炭的最佳工艺条件为:预处理后的核桃壳以53%氯化锌浸渍处理后用微波进行活化,微波火力中高火,辐射时间19min,料液比1:9,此时,活性炭的亚甲基蓝值可达11.36mL/0.1g。
Assisted by microwave activation technology,the raw materials of Xinjiang thin-skinned walnut shell was studied to prepare granular activated carbon. By response surface methodology, optimization processing parameters were determined as follows：after pretreatment,walnut shell was dipped into .53% zinc chloride solution with solid-to-liquid ratio of 1：9 and activated by microwave energy with high-fire for 19min, methylene blue value of the activated carbon could reach 1L.36mL/0.1 g.
