负载氯磷灰石的生物炭复合材料及其制备方法
摘要：
本发明公开了一种负载氯磷灰石的生物炭复合材料及其制备方法，该生物炭复合材料包括生物炭和氯磷灰石，氯磷灰石负载在生物炭上。其制备方法一为将竹屑粉末与氯磷灰石悬浮液混合，搅拌，离心，去除上清液，将所得的混合物进行煅烧，研磨，得到负载氯磷灰石的生物炭复合材料。制备方法二为将生物炭与氯磷灰石悬浮液混合，搅拌，离心，去除上清液，干燥，研磨，得到负载氯磷灰石的生物炭复合材料。本发明负载氯磷灰石的生物炭复合材料对重金属稳定效果好，具有比表面积大、成本低、能够显著降低重金属毒性的优点，是一种环境友好型的生物炭复合材料，其制备方法具有制备成本低、操作简单的优点。
摘要（英）：

The invention discloses a chlorapatite loaded biological charcoal composite material and a preparation method thereof. The biological charcoal composite material is prepared from biological charcoal and chlorapatite, wherein the chlorapatite is loaded on the biological charcoal. A preparation method I of the biological charcoal composite material comprises the following steps of mixing bamboo dust powder with chlorapatite suspending liquid, agitating, centrifuging, removing supernatant liquid, calcining an obtained mixture, and grinding, so as to obtain the chlorapatite loaded biological charcoal composite material. A preparation method II comprises the following steps of mixing the biological charcoal with the chlorapatite suspending liquid, agitating, centrifuging, removing the supernatant liquid, drying, and grinding, so as to obtain the chlorapatite loaded biological charcoal composite material. The chlorapatite loaded biological charcoal composite material provided by the invention has a stable effect on heavy metal, has the characteristics of large specific surface area, low cost and capability of obviously decreasing the toxicity of the heavy metal, and is an environment-friendly biological charcoal composite material. The preparation methods of the biological charcoal composite material have the advantages of low preparation cost and simple operation.
