Abstract
In this work the use of a mobile phone as a spectrophotometer using camera resolution by installing the software (application store AAP) on the phone (i Phone 6), which analyzes the colour images (RGB) in results with a colour length where it was possible to calculate the colour value of each image representing a specific concentration of the solution under study. A calibration curve with a range of (1 × 10-3 - 6.25 × 10-4) mmole.L-1 using optical image analysis with the concentration of the preparation of potassium permanganate (KMnO4). A calibration curve for statistical correlation range of 0.993 (R2) was found.
Keywords: Smartphone, UV-visible spectrophotometer, potassium permanganate.
