Preparation of Nano- Natural Betalain Pigments from Red Beet Roots with Some Metals and Study the Physical Properties of these Compounds
Hamdy Abdel Baky Matter, Tariq Mohamed Ayad and Abdel Rhman Elkatly

Betalain dyes are extracted from beetroots by ethanolic method and determined the concentration of Betalain dyes spectrophotometrically at λ max = 480 nm, calibration curve is draw with straight line at 501000 ppm. Effect of pH and physical properties of Nano-compounds are measured for Ni2+, Hg2+, Pb2+, Co2+, Cd2+, Bi2+ and Sb2+ ions.  The particles which precipitate by betalain dyes with metal ions Hg2+, Pb2+, Co2+, Cd2+, and Bi2+ are measured the conductivity which indicate that these Nano- metal dyes may be used as photo-electric cells.
