摘要：A method for the extraction and determination of thorium ions in water samples using (iso)polioxometalates sorbents and spectrophotometry with arsenazo (III) is proposed. The preconcentration step was studied with regard to experimental parameters such as amount of sorbents, type and amount of eluent, pH, flow rates and chemical interference of diverse ions on the recovery of thorium ion. The proposed method will be applied to the recovery of thorium ion from different water samples in order to determine the limit of detection of the proposed method.
