Removal of low level americium-241 from potable water originated from different geochemical environments by calcium alginate

► Decontamination of potable water from Am-241 without disturbing the water qualities. ► Decontamination is achieved by using calcium alginate beads complimented by activated charcoal treatment. ► Impact of origin of potable water on the decontamination process. ► Spectroscopic (ATR-FTIR) investigation of Am binding with calcium alginate at pH 4.0. ► Evaluation of the sorption capacity of calcium alginate for Am3+ based on Eu3+ a natural analog of Am.
