Determination of heavy metals in extracts and macerates from garden flowers Autori: , Simona Dobrinas, Viorica PopescuData aparitiei: July/August 2008 Revista: Environmental Engineering and Management Journal › Vol. 7 › Nr. 4 ISSN: 1843 - 3707 Format PDF Abstract
The aim of this work was to study the content of Fe, Mn, Zn and Pb in the mixtures which contain volatile oil between othercomponents, obtained after the Soxhlet extraction or maceration of the samples (different organs of garden flowers - blue hyacinthand chrysanthemum). The blue hyacinth is a bulbous perennial herb in the Lilliaceae family, grown for its showy and fragrantspringtime flower display. Garden chrysanthemums are tender perennials in the Asteraceae family in double-flowered forms.Flame atomic absorption spectrometry (FAAS) was used for the quantitative determination of metals in this matrix. Also, therefraction indexes and conductivity were measured using Abbe refractometer and LF 340-A conductometer, for thecharacterization of the obtained mixtures, respectively for correlation with the mineral content. It was observed that that ironconcentrations are higher in blue hyacinth extract and macerates than chrysanthemum. |
