摘　　要：以甘蔗渣为原料,经10%丁二酸对甘蔗渣进行处理,经丁二酸处理能显著提高其对Cd2+的吸附能力。分别考察甘蔗渣处理前后在不同初始浓度、时间、p H、吸附剂用量等因素条件下吸附Cd2+。实验结果表明处理过的甘蔗渣吸附最佳初始浓度为20 mg/L、吸附时间是1 h、p H为6、在60 mg/L镉离子溶液中吸附剂用量为0.6~1.0 g/100 m L。Bagasse purified by 10% succinic acid were used as the adsorption material, the adsorption capacities would be enhanced when bagasse purified by 10% succinic acid.The best condition of cadmium adsorption by purified bagasse, the influencing factors, such as initial concentration, adsorption time, pH values, and dosage of adsorption materials were focused on and discussed.The results of purified bagasse showed that Cd2＋initial concentration of 20 mg/L, adsorption time of 1 h, pH of 6, adsorbent dosage of 0.6~1.0 g/100 mL in Cd2＋concentration of 60 mg/L.
