英文摘要Raw peat was modified with sulfuric acid, then mixed modified with resin to prepare the modified peat resin particles. Using the batch experimental systems, the removal of heavy metals ( copper and lead) on the modified peat - resin particles was investigated. The data of the adsorption isotherm could be fitted by the Langmuir equation well. The adsorption rate of heavy metals on modified peat - resin particles was very swift. The removal processes of heavy metals on modified peat - resin particles could be well described by pseudo-second order model. The adsorption rate of lead was affected by the initial heavy metal concentration, initial pH, particle size, agitation speed and particle mass. In the adsorption of heavy metals ( lead and copper) on the modified peat - resin particles, ion exchange was the major reaction mechanism. Desorption data showed that the lead adsorbed by modified peat - resin particle could be desorbed by 0.5 N or 1.0 N HNO3. The desorption rate was swift. The experiments indicated that the modified peat - resin particles have great potential for the removal of heavy metals from wastewater.
