摘要
以牛骨为原料,通过高温煅烧牛骨制备羟基磷灰石(HAP),系统探究其最佳制备条件,结合X射线衍射光谱(XRD)、场发射电子扫描显微镜(SEM)、原子吸收光谱(AAS)等多种表征手段对其进行分析,并将所制备的样品应用于生活垃圾焚烧飞灰中重金属的固化研究。实验得出,在煅烧温度为400℃、煅烧时间为3h的条件下,得到的羟基磷灰石生成量最高,稳定性最好。固化实验表明:Cd的固化率为66.91%,Cr的固化率为61.97%,Cu的固化率为68.72%,Ni的固化率为67.75%,Pb的固化率为66.97%。
This study prepared hydroxyapatite(HAP)by high-temperature calcination of cattle bones and investigated its optimal preparation conditions.The synthesized HAP was characterized using XRD,SEM and AAS,and then applied to solidify heavy metals in waste incineration fly ash.The results showed that the highest yield and best stability of HAP were achieved at a calcination temperature of 400℃ for 3 hours.Solidification experiments demonstrated the following immobilization efficiencies:66.91%for Cd,61.97%for Cr,68.72%for Cu,67.75%for Ni,and 66.97%for Pb.
