Removal of low level americium-241 from potable water originated from different geochemical environments by calcium alginate
In a nuclear accident eventuality, the decontamination of potable water without disturbing the water quality is one of the major challenges.

| description | In a nuclear accident eventuality, the decontamination of potable water without disturbing the water quality is one of the major challenges. During this work, efforts have been made to reduce the contamination of americium (Am)-241 from potable water effectively by using calcium alginate followed by treatment with activated charcoal. Laboratory simulated experiments were carried out for the removal of low level of Am-241 from the potable water originated from groundwater, rain water and lake water. Water samples after filtering through 0.45
μm filter paper were spiked in the range of 10–200

It was observed that the variation of carbonate, bicarbonate, does not influence the sorption capacity of calcium alginate whereas the DOC decreased the sorption capacity in the range of 40–93% depending on DOC concentration.
