Description

一种磁性活性炭粉末
技术领域
本发明属于吸附剂技术领域，具体涉及一种磁性活性炭粉末。
背景技术
随着城市化进程的加快、城市人口的增加以及环保意识的加强，城市工业废水与生活污水的排放量日益增多，城市污水处理率也逐年提高，污水厂的污泥产生率也急剧增加。废水中的污染物结构复杂，难以生化降解，排放到环境中会对生态产生毒害作用，严重威胁到人类的健康。
目前，废水处理的方法有高级氧化法、膜处理法、吸附法等。其中高级氧化法除去效率高、速度快，但容易造成二次污染；膜处理法成本较高；吸附法操作简单、投资小，尤其对低浓度的污染物优势明显，利用吸附法去除水体中难降解有机污染物的研究收到了广泛关注。
活性炭是多孔吸附材料，具有丰富的孔隙结构、较高的比表面积以及很强的吸附能力。但是活性炭成本较高，制约着活性炭的推广应用。找到一种以吸附效果好又节约成本的吸附剂是亟待解决的问题。
发明内容
本发明的目的在于针对现有技术的不足，现提供一种吸附效果好、能重复循环利用、易分离的磁性活性炭粉末。
为解决上述技术问题，本发明采用的技术方案为：一种磁性活性炭粉末，其创新点在于：按重量份计，包括如下组分：六水合三氯化铁5-10份、四水合氯化亚铁5-10份、四氧化三铁10-20份、活性炭50-80份、氧化锌5-10份、醋丁纤维素10-20份、花生秸秆10-20份、硅酸镁5-8份、三氧化二铝5-8份、柠檬酸三乙酯5-10份、沸石5-10份、蒸馏水80-100份。
进一步的，所述四氧化三铁粒径为300-800nm。
进一步的，所述活性炭为油茶果壳活性炭、椰果活性炭或花生壳活性炭中的一种或几种。
本发明的有益效果如下：本发明在活性炭中掺杂磁性四氧化三铁，使得活性炭粉末吸附后易分离；本发明孩制备的活性炭吸附剂，可直接投入到废水中，操作简单，吸附完成后，通过磁场可实现吸附剂和水的分离，经过再生后可再次投入使用，重复利用性强、吸附效果好、性能稳定，大大降低了活性炭的投入成本。
