Synthesis of rhodamine dye derivative furan,determination of some heavy metals in environmental and food sampleby fluorimetric method

In this study, derivative of rhodamine dyes containing furan were obtainedto the literature.The synthesized products it is showed the fluorescence property. It is less the number of such molecules in the literature. Arsenic is an element highly dangerous for the environment and human health. People may be exposed to arsenic due to the polluted waters derive from industrial or agricultural chemicals, foods which grown in the rich arsenic soil, drinking waters, the dust and smoke. Arsenic is an element whichAs(III) and As(V) in the forms that having different degrees of toxicity. While the synthesized reagent(E)-2-((4,5-dimethylfuran-2-yl)-methyleneamino)-3',6'-bis-(ethyl-amino)-2',7'-dimethyl-spiro-[izoindol-1,9'-xanthene]-3-one (DMDB)and As(III) complexed, As(V) did not any complex. To determine thequantity of total arsenic in the real samples,KI + HCl + ascorbic acidmedium was performed to reduce. The quantity of As(III) was carried out using the developed procedure. After that, from total amount of arsenic, As(III) was removedthe quantity of As(V) was calculated. Keywords: Rhodamine, Furan, Arsenic, Speciation, Food samples.
