new method for the determination of iron (II) in a pharmaceutical preparation using the color intensity (RGB) of a smartphone

In this research, a new method was used to determine the amount of iron in pharmaceutical, by using color bio sensor smartphone device as for chromatic intensity samples images that are examined through program (color meter) is downloaded phone. An accessory mobile designed from plastic (black acrylic). form dark box inside equipped with flow cell and mirror reflecting flash light emitted green filter complementing red color, micro switch connected via earphones, attached case. The calibration curve range mg/L (1-8), correlation coefficient (R2) equal (0.999), limit detection (0.2) mg/L, relative standard deviation (RSD%) concentration (4) which examination repeated (10) times, its value (0.6 %), recovery (Recovery%) (101.5 %).
