Recognition of Liquid-liquid Two-phase Separation by Digital Image Processing

A simple digital image processing technique is examined to recognize the phase separation of a chemical process. traditional aqueous-organic hexane (1) - water (2) acetic acid (3) system and its alternative aqueous two-phase PEG (1)-K2HPO4 (2)-water was selected as model with or without polymer. In this technique, monitored recorded using webcam set up processed on computer an subtraction process determine net change in system. program written Python OpenCV programming language performed detect absolute changes over time from shot. The difference between initial aging evaluated. This gave recognition both systems regardless duration.
