Abstract:

采用自制木粉/壳聚糖接枝丙烯酸-丙烯酰胺吸附树脂R1、R2、R3对二元金属离子Cu2+/Pb2+和Zn2+/Pb2+溶液中的吸附性能进行了较系统考察。Pb2+离子溶液中存在竞争离子Cu2+、Zn2+时,随竞争离子浓度增加,3种吸附树脂R1、R2、R3对Pb2+的吸附量明显下降,而竞争离子吸附量显著增加。二元溶液中各金属离子浓度相同时,3种树脂对竞争离子Cu2+、Zn2+的吸附量大于对Pb2+的吸附量;各溶液中分别加入NaCl及NaNO3、尿素后,对Pb2+离子的吸附量下降迅速。随吸附树脂用量增加,竞争离子Cu2+、Zn2+的吸附量逐渐减小,Pb2+的吸附量在吸附树脂用量0.10g/L(Zn2+/Pb2+溶液)或0.15g/L(Cu2+/Pb2+溶液)时出现最大值。溶液pH值对树脂吸附性能有显著影响。3.02+的吸附量快速增大;52+的吸附量基本不变;92+的吸附量减小,而对竞争离子的吸附量或增大或减小。
