Characterization of nitrate ions adsorption and diffusion in P(DMAEMA/HEMA) hydrogels
摘要:
In this work, the adsorption and diffusion behavior of nitrate ions into polycationic P(DMAEMA/HEMA) hydrogels is analyzed. Experimental results indicated that nitrate ions can be removed efficiently from aqueous solutions. Adsorption isotherm of gels was well according to the Langmuir and Langmuir-Freundlich models. At the same time, the diffusion behavior of nitrate ions from P(DMAEMA/HEMA) hydrogels was investigated. The diffusion coefficients are strongly influenced by the changes of temperature and pH value of solutions. At the same time, D does not depend on the gels cross-linking ratio and initial solute concentration.
