2 g of seaweed was taken in a glass container. 10 ml of perchloric acid was added to it and left without disturbance for 5 min (to remove the organic constituents present in it). Then, 10 ml of concentrated nitric acid was added to it and incubated for 5 min and then added with 10 ml of HCl. The mixture was allowed to evaporate and the final residue was dissolved in 10 ml of Concentrated HCl. The filtrate was subjected to analysis in atomic absorption spectrophotometer (Perkin Elmer Analyst 800 with flame furnace). The minerals analyzed were Sodium, Potassium, Calcium, Iron, Magnesium, Lead and Zinc and the results were expressed as ppm.
