钢渣是一种商业废料，主要含有SiO2、Al 2 O3和CaO，它们分别是沸石和羟基磷灰石（HAP）的化学成分。以钢渣为原料，通过添加磷酸和氢氧化钠，在一次反应体系中成功合成了羟基磷灰石-沸石复合材料（HAP-ZE）。采用XRD、SEM、N2吸附等方法对HAP-ZE的结构特征进行了研究。从挥发性有机物的吸附，HAP-ZE被发现具有吸附性能的纯沸石和HAP。
Steel slag is a commercial waste material mainly containing SiO2, Al2O3, and CaO which are the chemical components of zeolite and hydroxyapatite (HAP), respectively. From the steel slag, a hydroxyapatite-zeolite composite material (HAP-ZE) was successfully synthesized in a one batch system by adding H3PO4 and NaOH. The structural characteristics of HAP-ZE were investigated by XRD, SEM, and N-2 adsorption. From the adsorption of VOCs, HAP-ZE was found to have adsorption properties comparable to those of pure zeolite and HAP.
