Determination of mineral and heavy metals in Cousinia stocksii, Eremostachys thyrsiflora and Gaillonia macrantha plants for health safety approaches by atomic absorption and flame photometry techniques. Pure and Applied Biology. Vol. 8, Issue 2, pp1571-1578. http://dx.
AbstractNine different elements (Cu, Co, Ni, Fe, Mn, Cd, Pb, Na and K) were determined in the three plant species i-e Cousinia stocksii, Eremostachys thyrsiflora and Gaillonia macrantha by FAAS and Flame photometer. Digestion of the plant samples were carried out by using tri-acid mixture (HNO3, H2SO4 and HClO4). The distribution order of the elements in the three species were:C. stocksii:Cd≈Pb≈Co
