摘要
以硼泥酸浸渣为吸附剂,研究了酸浸渣用量、初始质量浓度、温度、pH值和时间对吸附Cu2+的影响规律,并总结了其吸附模型。结果表明,酸浸渣对Cu2+的吸附量随温度、初始质量浓度、pH值的升高而增大。酸浸渣对Cu2+的吸附符合Langmuir等温吸附模型;酸浸渣对Cu2+的吸附动力学模型符合准二级动力学方程。
Sorption experiments with the acid leaching residue of boron mud as adsorbent were conducted to evaluate the effects of adsorbent doses, Cu^2+ initial concentration, temperature, solutions pH value and time on the sorption capacities of Cu^2+, and summarized its adsorption mode. The results showed that, the sorption capacity of CuE+ increased with the increase of temperature and solution pH value and the concenration of Cu^2+. The model of isothermal adsorption accorded more with Langmuir equation. The kinetic experimental data followed the second-order kinetic model.
