As and Pb are among the most important sorts of contaminant in the environment. Several methods already used to clean up the environment from these ions, but most of them are costly and difficult to get optimum results. Currently, phytoremediation is an effective and affordable technological solution used to extract or remove inactive metals and metal pollutants from contaminated soil samples. In this work, we investigated the monitoring of As and Pb in Populus alba and Typha latifolia samples. Plant samples were collected from Mazandaran and West Azerbaijan States. After the extraction elements was eluted with HNO3 1% v/v and was analysed with Agilent 7700x ICP-MS and Perkin-Elmer 5100 ZL (CT, USA) atomic absorption spectrometer with Zeeman background correction instruments. The developed method can be applied in phytoextraction and matalomics studies. The effect of experimental parameters on the extraction performance including pH, volume and concentration of aqueous solution and volume of eluent solution and amounts of were investigated. Under these extraction conditions, determination by ICP-MS and GF-AAS was able to provide a good linearity (R2 ≥0.9997) in the range of 0.08–3800.0 and 0.10-3750.0 ng mL−1, low limit of detection (0.02 and 0.04 ng mL−1), good extraction repeatabilities (relative standard deviations below 2.1% and 1.9%, n = 10), and enrichment factor of 40. Finally, the developed method was successfully used for the determination of the mentioned analyte in Populus alba and Typha latifolia samples. Recoveries in real samples were between 81.6% and 91.7.%
