摘　　要：通过液相合成法制备了竹炭/羟基磷灰石复合材料.研究了竹炭与羟基磷灰石的配比、吸附时间、溶液的pH值、温度以及复合材料用量等因素对复合材料吸附Cu2+效果的影响.研究结果表明:竹炭与羟基磷灰石的质量比为3/5,在pH值为5～6条件下吸附120 min,竹炭/羟基磷灰石复合材料对Cu2+吸附效果最佳,吸附率可达96.08%,同时复合材料对Cu2+吸附受温度影响不大.认为竹炭/羟基磷灰石复合材料可作为除铜吸附材料.The charcoal/hydroxyapatite composite was prepared by liquid synthesis method.And the effect of ratio of bamboo charcoal to Hap,absorbing time,pH,temperature and quantity of absorbent on the adsorption rate to Cu ion were studied.Results showed that the composite could effectively remove Cu ion with high adsorption capacity when the ratio of bamboo charcoal to HAp is 3/5.The adsorption rate of composite for Cu ion can achieve up to the best result of 96.08 percent when pH is 5-6 at 120 min.The adsorption rate of composite for Cu ion would not be affected by temperature.The bamboo charcoal/HAp composite can be used as absorption material for the removing of Cu adsorbing material.
