Latar Belakang: Aplikasi zat warna alam yang terdapat di dalam sayur atau buah-buahan dalam analisis logam dapat digunakan dengan tujuan mengurangi perncemaran terhadap lingkungan. Betanin merupakan salah satu zat warna yang diketahui berpotensi sebagai zat pengompleks di dalam analisis logam dengan metode spektrofotometri UV-Vis. Potensi betanin sebagai zat pengompleks disebabkan karena keberadaan logam dapat mempengaruhi kestabilan warna betanin dan menyebabkan efek batokromik atau hipokromik. Tujuan: Penelitian ini bertujuan sebagai studi pendahuluan penggunaan betanin sebagai senyawa pengompleks dalam analisis logam Pb menggunakan metode Spektrofotometri Uv-Vis.. Metode: Penelitian ini dilakukan dengan mereaksikan antara larutan Betanin dengan larutan Standar Pb, kemudian kompleks yang terbentuk diukur serapannya menggunakan Spektrofotometri Uv-Vis pada Panjang gelombang maksimumnya. Hasil: Hasil penelitian diperoleh bahwa dengan berbagai variasi konsentrasi larutan standar Pb, absorbansi dari kompleks Betanin-Pb sesuai dengan Hukum Lambert-Beer dan diperoleh persamaan garis Y = 0,0066x + 0,5388 dengan R2-0,9991. Kesimpulan: Berdasarkan hasil penelitian yang diperoleh, diketahui bahwa Betanin dapat digunakan sebagai alternatif sebagai senyawa pengompleks pada analisis logam Pb dengan metode Spektrofotometri UV-Vis.

“…The determination of Pb(II), Cu(II) and Ni(II) [16,17] has aroused interest among researches, since these cations are present simultaneously in a wide range of real samples. It has been undertaken with a number of different tech and on very varied matrices, by means of ICP (Inductively Coupled Plasma) and GFAAS (Graphite Furnace Atomic Absorption Spectrometry) in edible oils [18] and in alloys by means of ETAAS (Electrothermal Atomic Absorption Spectrometry) [19].…”

Aims: Since the end of the nineteenth century, when Werner proposed his theory of co-ordination, the study of metallic compounds has continued to attract the interest of researchers. The present work had as its aim to achieve simultaneous determination of Pb(II), Cu(II) and Ni(II) by means of UV-VIS and derivative spectrophotometry, using methyl-ethylene-diamine-tetraacetic acid, MEDTA, as a chelating agent. Study Design: The visible and ultraviolet spectroscopy allows both to identify a chemical substance (qualitative analysis) and to determine its concentration (quantitative analysis). In the work, the UV-VIS and derivative spectrophotometry is used for the determination simultaneous of Pb(II), Cu (II) and Ni (II). The method proposed uses methyl-ethylene-diamine-tetracetic acid (MEDTA) as a chelating agent and absorption spectrophotometry for quantification.

Recently, the growing attention of the scientific community has been focused on the threat to health created by environmental pollutants, including toxic metals such as cadmium (Cd), and on the need of finding effective ways to prevent and treat the unfavorable health effects of exposure to them. Particularly promising for Cd, and thus arousing the greatest interest, is the possibility of using various ingredients present in plants, including mainly polyphenolic compounds. As the liver is one of the target organs for this toxic metal and disturbances in the proper functioning of this organ have serious consequences for health, the aim of the present review was to discuss the possibility of using polyphenol-rich food products (e.g., chokeberry, black and green tea, blueberry, olive oil, rosemary and ginger) as the strategy in protection from this xenobiotic hepatotoxicity and treatment of this heavy metal-induced liver damage. Owing to the ability of polyphenols to bind ions of Cd and the strong antioxidative potential of these compounds, as well as their abundance in dietary products, it seems to be of high importance to consider the possibility of using polyphenols as potential preventive and therapeutic agents against Cd hepatotoxicity, determined by its strong pro-oxidative properties. Although most of the data on the effectiveness of polyphenols comes from studies in animals, the fact that some of them are derived from experimental models that reflect human exposure to this metal allows us to assume that some polyphenol-rich food products may be promising protective agents against Cd hepatotoxicity in humans.
