Phenol and/or Zn2+ adsorption by single- or dual-cation organomontmorillonites
Source abstract
Abstract
Abstract Single- or dual-cation organomontmorillonites (OMt) modified by one or two cationic surfactants, respectively and/or cysteamine hydrochloride (CSH) were used to remove Zn 2 + and/or phenol from aqueous solutions. The OMt were characterized by XRD, FTIR spectroscopy and N 2 adsorption-desorption isotherm analyses. The adsorption results of Zn 2 + and phenol showed that OMt had much larger adsorption capacities of phenol than that of Na + -Mt or CSH-Mt in the presence of Zn 2 + . Experiments with the simultaneous presence of both the contaminants showed that one did not affect the adsorption of the other with all the adsorbents. The uptakes of Zn 2 + and phenol onto dual-cation OMt increased with increasing solution pH, contact time, temperature and initial concentration of Zn 2 + and phenol. The adsorption equilibrium time was 10 min for both contaminants and the maximum adsorption capacities of Zn 2 + and phenol were found under alkaline environment. The adsorption of both Zn 2 + and phenol can be better described by Freundlich model than Langmuir isotherm. Phenol adsorption onto OMt was caused primarily by partitioning into an organic phase in the interlayers, and the uptakes of phenol increased with increasing alkyl chain length and loading amount of surfactant in single-cation OMt. Zn 2 + adsorption onto dual-cation OMt was due to ion exchange, formation of complexes and/or precipitation mechanism depending on the solution pH.
