甘蔗渣对铅离子的吸附性能研究

Sugarcane Bagasse for Adsorption Properties of pb^(2+)

研究了甘蔗渣对水中pb^(2+)的吸附性能,包括吸附时间、吸附温度、pb^(2+)初始浓度、pH、吸附剂投加量。结果表明:吸附温度对吸附率的影响不大,在反应时间为60min,pH为7的条件下,甘蔗渣对低浓度pb^(2+)有较高的吸附率,水中pb^(2+)的初始浓度越低,吸附率越高。

The adsorption properties of sugarcane bagasse were investigated. The results showed that, temperature had little influence on adsorption properties; under the condition the adsorption time was 1 h, the p H value was 7, it had higher adsorption rate when low initial concentration of pb（2＋）; the lower initial concentration of pb（2＋）, the higher adsorption rate.
