A novel nanozirconium tungstovanadate that was assigned as a cation exchanger was synthetized using sol-gel preparation technique. The response of synthesis parameter variation on the properties of the produced ion exchanger was elucidated. The reactant molar ratio, gelation temperature, and HCl concentration have been optimized to attain cation exchanger with high ion exchange capacity and lead ion sorption. The most proper prepared sample has been chemically and physically characterized using different techniques. The ion exchange capacity of this sample was 2.5 meq/g and it recoded 96% lead ion sorption. The effects of the different processing parameters that affect lead sorption process have been investigated by a single factor method. Langmuir and Freundlich isotherm models were applied to the experimental data to examine the lead uptake mechanism.
