Abstract

本发明涉及一种新型砷吸附材料，该材料是由一种固体废弃物简易加工而成，廉价易得，通过该材料可以高效吸附去除水中的砷。

Description

一种新型砷吸附材料
技术领域
本发明涉及一种新型高效吸附砷的材料，属于新材料技术领域。
背景技术
近年来，随着工农业和采矿、冶金等产业的蓬勃发展，在一定程度上加重了水资源的污染，导致地下水和地表水中砷的含量严重超标。高砷水在满足人类用水的同时也给人们带来了致命的伤害，即所谓的地方性砷中毒，地方性砷中毒长期困扰着人们，并且砷的强致癌性也提醒着人们，为了人类自身的生命健康与安全，必须开发高效经济且环保的饮用水及工业废水除砷工艺。
因此，近年来各国学者对砷的去除技术进行了大量研究，目前发展较为成熟的砷去除技术主要有以下几种：沉淀法、吸附法、离子交换法、膜技术和生物技术等。吸附法是通过物理作用、化学作用或离子交换等将水中的砷固定在吸附剂的表面，从而将砷去除的方法。吸附法是一种简单易行的水处理技术，在我国应用的最为广泛，目前，在水处理中常用的砷吸附剂有活性氧化铝、活性炭、沸石等。活性氧化铝虽然对As(V)具有良好的去除效果，但通常在pH值为5左右时这种效果才能很好的表现出来，从而限制了其应用；而活性炭和天然沸石对砷的吸附能力又相当有限。因此，研究新型廉价、吸附性能优良的吸附剂是除砷的关键。
发明内容
本发明的目的是客服现有砷吸附剂吸附容量小的不足，提供一种具有高吸附容量的新型砷吸附剂。
为达到上述目的，本发明将提供一种新型砷吸附剂，即将蜂窝煤煤渣破碎后过100目筛，在105℃条件下烘干后所得的材料。
上述新型砷吸附材料的特征在于其原材料蜂窝煤煤渣属于一种固体废弃物，对环境友好，廉价易得。
上述新型砷吸附剂具有如下有益效果：将上述材料6g投加到100ml含砷的溶液中，在160r/min，25℃摇床中恒温振荡3小时，可以将溶液中20mg/L的砷降至0.94mg/L，将溶液中15mg/L的砷降至0.42mg/L，将溶液中10mg/L的砷降至0.15mg/L，将溶液中6mg/L的砷降至0.02mg/L。
具体实施方式
蜂窝煤煤渣是一种工业固体废弃物，本发明所述的新型砷吸附材料即为将蜂窝煤煤渣破碎后过100目筛，105℃条件下烘干所得的产物，用于吸附溶液中的砷。
将适量上述材料投加到含砷的溶液中，在160r/min，25℃摇床中恒温振荡，待吸附完全后，测定溶液中砷的浓度。
通过上述方法即可将溶液中的砷吸附去除。
