摘要
通过室内分析的方法研究了天然沸石对NH4+离子的吸附及解吸动力学影响。结果表明,天然沸石对NH4+的吸附和解吸动力学符合一级动力学方程、修正的Freundlich方程、抛物线扩散模型和异分子扩散模型。沸石对NH4+的解吸速度很快,在60min内解吸完全。
The adsorption and desorption kinetic of natural zeolite on NH4^＋ was studied by lab analysis. The results showed that the adsorption and desorption kinetic of natural zeolite on NH4^＋ was eoineided with the first-order kinetics, modified Fre- undlich equation, parabolie diffusion model, and heterogeneous diffusion model. The desorption of the adsorbed NH4＋ was far more rapid than the adsorption, the desorption was complete in 60 min.
