Spectrometric study on the interaction of Sn(Ll) and Fe(Ll) with natural pigment of hibiscus rosa-sinensis / Masni Hassan

Hibiscus rosa-sinensis flowers of different colors (pink, peach and red) were chosen in these spectrophotometric studies. The natural pigments were extracted in acidified water with hydrochloric acid at different pH (1, 3, and 5). The crude extract was then analyzed by using UV-VIS Spectrophotometer...
