Oxygen Reduction Analysis

Below is a python program coded by myself, Forrest Nichols, and Ryan Lee capable of reading a csv file containing raw data from an ORR study and outputting three plots as well as csv files containing the coordinates of those plots. The program also outputs the Tafel slope and R squared value.

Plots made in the program:

The Koutecky-Levich
Tafel
Electrons Transferred

Each plot follows from the associated equation given below:

Koutecky-Levich Equation:

Tafel Equation:

Electrons Transferred Equation:

Python Program:

CompleteORRAnalysis.py

Example Starting file:

This will need to be converted to a csv

PtCORR.csv

Here are example images output by the program

Along with the below images, the python program also creates three csv files containing the coordinates of each plot to be used in software programs such as SigmaPlot or Microsoft Excel.
