Pyrolysis presents a promising solution for the complete purification and recycling of waste salt. However, presence organic pollutants in salts significantly hinders their practical application, owing to diverse sources strong resistance degradation. This study developed predictive models removal from salt using three machine learning techniques: Random Forest (RF), Support Vector Machine, Artificial Neural Network. The were evaluated based on total carbon (TOC) rate mass loss rate, with RF model demonstrating high accuracy, achieving R2 values 0.97 0.99, respectively. Feature engineering revealed that contribution components was minimal, rendering them redundant. importance analysis identified temperature as most critical factor TOC removal, while moisture content nitrogen key determinants loss. Partial dependence plots further elucidated individual interactive effects these variables. validated both literature data laboratory experiments, user interface Python GUI library. provides novel insights into pyrolysis process establishes foundation optimizing its application.
