【摘要】 研究了氧化原位固化黑荆树皮(YYGHS)对金属离子的吸附特性.结果表明原位固化黑荆树皮(YGHS)经氧化后对Cu2+、Zn2+、Ni2+吸附量增加450%以上.在25℃、pH值4.82和Cu2+的初始质量浓度为272 mg.L-1的条件下,YYGHS对Cu2+的吸附量达到44.3 mg.g-1.在本实验条件下YYGHS对Cu2+的吸附符合拟二级速度方程和Langmuir吸附等温方程.更多还原

【Abstract】 The adsorption characterization of modified barks of black wattle to metal ions was investigated.The results showed that the oxidization of n-situ immobilized barks of black wattle resulted in the increase of more than 450% in adsorption capacities of the bark to Cu2+,Zn2+ and Ni2+.The adsorption capacity of the bark to Cu2+ was 44.3 mg·g-1 at 298 K when the initial concentration of Cu2+ and pH value was 272 mg·L-1 and 4.82,respectively.The adsorption of Cu2+ on the bark can be described by pseudo-second-order rate equation and Langmuir equation.更多还原
