中文摘要	研究了以工业石膏为原料合成羟基磷灰石(HAp)的方法,并考察了所制备的HAp对水溶液中Pb2+,Cu2+,Zn2+和Ni2+四种金属离子的吸附作用.结果表明,在反应温度90℃、磷酸氢二铵和工业石膏物质的量比为1:2的条件下,反应24h便可以得到较纯的HAp.所制备的HAp在pH7的条件下对水溶液中的Pb2+,Cu2+,Zn2+和Ni2+均具有一定的吸收能力,其饱和吸附量分别为1095,86.76,64.68和67.90mg/g.该吸附过程符合Langmuir吸附模型.; The preparation method of hydroxyapatite(HAp)with industrial gypsum was investigated.The adsorption abilities of as-prepared samples upon Pb2 +,Cu 2+,Zn 2+and Ni 2+ions in aqueous solution were examined.It was indicated that pure HAp could be successfully fabricated when the molar ratio of(NH4)2HPO4 to industrial gypsum was 1:2 with the reaction between them for 24 h under 90℃.The as-synthesized HAp exhibited obvious adsorption ability upon Pb2 +,Cu 2+,Zn 2+and Ni 2+ions under pH 7,and their saturated adsorption amounts were 1 095,86.76,64.68 and 67.90 mg/g respectively.Their adsorption behaviors could be described with the Langmuir model approximately.
